Feature of CSI Bridge 26.0.0 Build 2899:

• User Interface
  • Fully Personalized Graphical User Interface
    • For the purposes of modeling, analysis, design, scheduling, load rating, and reporting, CSiBridge provides a single user interface.
  • slick DirectX graphics
    • The DirectX graphics option has been improved to use DirectX 11 for faster and more powerful performance. Quick rotations and model navigation are made possible using DirectX 11 graphics.
  • Several Views on a Single Screen
    • On a single screen, you may see load allocations, moment diagrams, deflected forms, design output, and reports. The new display enables the presentation of all loads on all object types inside a single load pattern on a single display.
  • Advanced Tools for Shortcuts
    • The menu interface incorporates keyboard shortcut keys and allows for customisation of the shortcuts. An Apply button has been added to many Edit, Assign, and Select menu forms, enabling them to stay open for repeated usage.
  • Forms That Float
    • The ability to keep assign and pick menu forms open for frequent usage has been improved.
• Modeling
  • Flexible Modeling Tools to Build a Variety of Bridge Types
    • Common concepts used in bridge engineering, such as layout lines, spans, bearings, abutments, bents, hinges, and post-tensioning, are used to define the bridge models parametrically. The bridge object model is used to control the parametric model. The full analytical model, which includes the deck sections, diaphragms, bearings, restrainers, foundation springs, superstructure variation, abutments, bents, hinges, tendon layouts, and more, is composed of a finite element assembly known as the bridge object model. Either a 2D basic model technique or a 3D refined model approach may be used to examine bridge models.
  • A Vast Range of Templates for Quick Model Creation
    • By using Quick Bridge Templates, CSiBridge provides a practical and quick method for modeling bridges. They provide a great foundation for a model that can then be adjusted as required.
  • Editing Databases Interactively
    • Modifying model data in a table view using interactive database editing makes updating the model a simpler process. Tables from Microsoft Access and Excel may be readily imported and exported.
  • Automated Generation of Section Cuts
    • At each unique station point, section cuts are produced for both the individual beams and the full bridge deck. Users may specify the station points.
•  Parametric Bridges Modeling

• • Bridge Master
    • With instructions at every stage to guarantee that all required components are described in the model, the Bridge Wizard is an effective tool that leads you through the process of creating a full bridge model step-by-step.
  • Arrangement Lines
    • The bridge’s highway layout is delineated by its layout lines. They may be defined using PI (point of intersection) inputs or bearing and station notation inside CSiBridge. You may import them by using a file called LANDXML. The whole bridge structure and its parametric geometry are updated when layout lines are changed.
  • Templates for Superstructure Deck Sections
    • Precast I and U girders, steel I and U girders, concrete box girders, and more are among the many parametric deck sections available from CSiBridge. The bridge deck section specification may be produced with accuracy by using the parametric configuration of each deck segment.
  • Subdivision
    • CSiBridge allows for the very precise modeling of bridge substructures, such as bents, abutments, restrainers, bearings, and foundations. P-Y springs or 6X6 linked springs are two types of foundation springs that are used on different foundation components. Link elements that are either linear or nonlinear may be used to represent foundation springs.
  • Diaphragms
    • Diaphragms may be found at the spans’ ends and at the supports. Concrete, steel girder, and intricate steel cross-frames are among the types. These might be uneven and lopsided. For steel U-girders, interior cross frames may also be supplied.
  • Variations in Parametrics
    • By applying parametric variations, the deck section parameters, such as girder spacings, deck and overhand widths, depths, and more, may be changed for the bridge model. By defining variations parametrically, modeling a bridge takes a lot less time.
  • Following Tensioning
    • Use the enhanced options for arranging tendons and forces to define post-tensioning in CSiBridge. The drape positions inside the tendon will be automatically assigned by CSiBridge when designing box girders, but the engineer may also modify them. Segmental bridges may have fully auto-generated tendon systems.
  • Lanes
    • Determine the lanes as soon as possible using the bridge’s layout lines. One may categorize lanes as either floating or fixed. Influence lines or surfaces are used to make the most important reaction for every element in the bridge model.
• Structural Elements
  • Easily manage joints, frames, and solid elements
    • When meshing structural items, CSiBridge automatically produces joints at the intersections of structural objects or at internal joints. It is possible to show joint coordinates, assignments, and displacements in tabular or screen format.
  • Columns / Beams
    • In order to account for the effects of biaxial bending, torsion, axial deformation, and biaxial shear deformations, the frame element employs a universal, three-dimensional beam-column formulation. A built-in library of standard US and worldwide standard section characteristics for steel, concrete, and composite sections is included in CSiBridge.
  • Unfocused Segments
    • It is easy to define even non-prismatic and built-up steel pieces. The steel beam editor form makes it simple to define steel I- and U-girder sections.
  • Section Chief
    • Section Designer is an integrated tool that facilitates the modeling and analysis of unique cross sections. It is included in SAP2000, CSiBridge, and ETABS. The assessment of member characteristics and nonlinear response, such as nonlinear hinge and PMM-hinge behavior, may be done with the help of Section Designer.
    • A vast array of structural components are available for analysis and design.
    • For practical application, CSiBridge has a large range of structural components for analysis and design that are fully integrated.
  • Shells
    • • One kind of area object used to simulate membrane, plate, and shell behavior in two- and three-dimensional systems is the shell element. When using a layered shell, material nonlinearity may also be taken into account. The shell material may be homogenous or layered throughout.
  • Wire Component
    • The cable element simulates thin tension elements that can not sustain bending moments but may transport axial loads in a draped manner. Authentic catenary activity that adjusts to the applied weight is captured at higher licensing levels. Nonlinear static, staged, and direct-integration load scenarios all inevitably include tension stiffening and large-displacement behavior. For many constructions where just tension-stiffening effects are needed and the cable form is known, lower license levels without catenary behavior are adequate. For information on the behavior that is enabled by various licensing levels, see the item “Cables – Nonlinear Catenary Behavior” below.
  • Tendon Component
    • With geometry defined as straight lines, parabolas, circular curves, or other arbitrary forms, tendon drawings are simple and autonomous objects. Tendon loads in CSiBridge may be specified with ease, including all losses. Tendons may also be introduced to girders and spans of bridges by using readily editable template profiles. Tendons may be seen as loads or components.
  • Sturdy Component
    • For modeling solids and three-dimensional structures, the solid element has eight nodes. Based on an isoparametric formulation, it may be used to modeling objects whose thickness affects loads, boundary conditions, section characteristics, or reactions. It has nine alternative incompatible bending modes.
  • Connecting Element
    • Depending on the kind of attributes supplied to it and the kind of analysis being done, a link element may behave in one of three ways: linear, nonlinear, or frequency dependent. The CSiBridge link components include friction isolators, rubber isolators, T/C isolators, gaps, hooks, dampers, linear, multi-linear elastic, multi-linear plastic, frequency-dependent springs, and frequency-dependent dampers.
  • Springs
    • Link components, such as spring supports, are used to unite joints to the ground or to adjacent joints. Their nature might be either nonlinear or linear. Gaps (only in compression), viscous dampers, multi-linear elastic or plastic springs, and base isolators are examples of nonlinear support conditions that may be modeled.
  • Fasteners
    • In CSiBridge, hinge characteristics may be generated and used to carry out pushover or nonlinear time history investigations. Fiber hinges may be used to mimic nonlinear material behavior in frame components (beam, column, and brace). With this method, the material in the cross section is represented as discrete points that each precisely match the material’s stress-strain curves. It is possible to depict mixed materials, such as intricate forms and reinforced concrete.
• Filling up
  • Use Auto Loadings to Boost Productivity
    • Based on a variety of national and international norms, CSiBridge will automatically create and apply seismic and wind loads. You may apply moving loads to lanes with CSiBridge thanks to its advanced moving load generator.
  • Earthquake
    • When the auto seismic design is enabled, CSiBridge will automatically produce seismic demands and compare those needs to member capabilities. When calculating the capacity displacements for bridges with a Seismic Design Category D, a pushover analysis may be used.
  • Wind
    • CSiBridge uses a variety of national and international codes to automatically create and apply wind loads. User-defined wind loads are another option.
  • Transferring Loads
    • In order to ascertain the greatest reactions to each bridge element, moving loads may be applied to either fixed or floating lanes. Vehicle classes or specific vehicles may be used to apply moving loads.
    • Use the User Loads application to define a broad range of loading conditions.
    • With the built-in user loading choices in CSiBridge, you may define unique loads to simulate utilizing a broad range of loading circumstances. In addition, loads may be imposed parametrically as wet concrete loads, area, line, and point loads.
  • Momentum and Force
    • Applying concentrated forces and moments at the joints and along the frame parts is done with the help of the force load. Both distributed and trapezoidal loads are included in this. Values may be expressed in the joint local coordinate system or a fixed coordinate system (global or alternative coordinates).
  • Moving Away
    • The impact of support settling and other externally forced displacements on the structure is represented by displacement loading. Both linear and nonlinear spring supports as well as constraints may be used to exert displacement loading. For structures as well, multiple-support dynamic excitation may be taken into consideration.
  • The temperature
    • The Frame element experiences thermal strain due to the Temperature Load. The product of the element’s temperature change and the material’s coefficient of thermal expansion determines this strain. For a linear analysis, all given temperature loads indicate a temperature change from the unstressed condition; for a nonlinear analysis, the temperature change is from the prior temperature. It is also possible to apply temperature gradients as temperature loads.
• Evaluation
  • CSiBridge is capable of handling several kinds of analysis.
    • Static, staged construction, multi-step static, modal, response spectrum, time (response) history, moving load, buckling, steady state, and other choices are available for CSiBridge load cases.
  • Transporting Static Loads
    • A vehicle class may run in one or more lanes; this allows you to apply loads. The analysis will take into account all possible combinations of vehicle classes using the designated traffic lanes in the load scenario.
  • Changing Loads: Adaptive
    • Complex loading patterns may be achieved by combining many occurrences of a single vehicle working on a single lane or rail-track in a multi-step load pattern. The car may go forward or backward for each instance, with a predetermined beginning point, start time, and speed.
    • For both linear and nonlinear analysis, there are several potent dynamic analysis tools accessible.
    • Response-spectrum analysis, time-history analysis, and the computation of vibration modes using Ritz or Eigen vectors are some of the dynamic analysis features offered by CSiBridge for both linear and nonlinear behavior.
  • Spectrum of Responses
    • A response-spectrum study establishes a structure’s statistically probable reaction to seismic loads. Rather than using time-history ground motion data, this linear form of analysis makes use of response-spectrum ground-acceleration records depending on the seismic load and site parameters. This approach is quite effective and considers the structure’s dynamic nature.
  • Temporal History
    • The step-by-step reaction of structures to seismic ground motion and other forms of loading, such as explosion, machinery, wind, waves, etc., is captured by time-history analysis. Both linear and nonlinear analysis techniques—modal superposition and direct integration—can be used.
    • Strong tools for nonlinear analysis related to material or geometric response
    • When either geometric or material nonlinearity is taken into account during structural modeling and analysis, nonlinear analysis techniques work best.
  • Non-linear Fastening
    • An incremental application of the whole load is made during nonlinear-static buckling analysis. At every step, stiffness and reaction are assessed. P-delta, large-displacement, and/or nonlinear material behavior influences may cause stiffness to vary between each displacement step. The findings of nonlinear-static buckling analysis are often more realistic than those of linear buckling analysis because it takes material nonlinearity into account while producing the buckling response.
  • Delta P
    • The softening impact of compression and the stiffening effect of tension are captured by P-delta analysis. For linear load scenarios, the stiffness may be changed using a single P-delta study under gravity and sustained loads. These analyses can then be superposed. As an alternative, complete nonlinear P-delta effects may be examined for every load combination. All aspects have P-delta effects, which are easily included into analysis and design.
  • Time History of Direct Integration
    • For a broad range of situations, the nonlinear modal method—also known as FNA for Fast Nonlinear Analysis—is very precise and efficient. Even more versatile, the direct-integration approach can deal with significant deformations and other very nonlinear phenomena. A variety of applications may be addressed by chaining nonlinear time-history studies with other nonlinear situations, such as staged building.
  • buckling
    • A structure may have linear (bifurcation) buckling modes under any combination of loads. One may compute buckling from a staged-construction or nonlinear condition. Complete nonlinear buckling analysis that takes into account the impacts of P-delta or significant deflections is also included. By combining displacement control and static analysis, snap-through buckling behavior may be recorded. Follower-load issues, which include more intricate buckling, may be modeled using dynamic analysis.
  • Phased Development
    • With CSiBridge, you can define a series of stages for staged construction, a type of nonlinear analysis that enables you to add or remove structural elements, apply loads to specific sections of the structure selectively, and take time-dependent material behavior like creep, aging, and shrinkage into account.
  • Phased Construction Phases
    • Staged construction, sometimes referred to as segmental, incremental, or sequential building, is a technique for altering, adding, or subtracting different structural components.
  • Shrinkage and Creep
    • Staged sequential construction analysis may be used to calculate long-term deflections caused by shrinkage and creep. In order to calculate creep stresses, time-dependent material characteristics are based on user-defined curves, ACI 209R, CEB FIP, and other codes.
  • Pushover Static
    • The application of ASCE 41, AASHTO/Caltrans, and the hinge and fiber hinge option based on stress-strain are some of the pushover analysis elements of CSiBridge.
  • Layered Nonlinear Shell
    • You may take into account the plastic behavior of slabs, steel plates, concrete shear walls, and other area finite components in the pushover analysis by using the nonlinear layered shell element. For hinges made of concrete and steel, force-deformation relations are established.
  • vivacious
    • Response-spectrum analysis, time-history analysis, and the computation of vibration modes using Ritz or Eigen vectors are some of the dynamic analysis features offered by CSiBridge for both linear and nonlinear behavior.
  • Moderate
    • Eigen-vector modal analysis determines the structure’s natural vibration modes, which serve as the foundation for modal superposition in response-spectrum and modal time-history load scenarios as well as a means of comprehending the behavior of the structure. Ritz-vector modal analysis is more effective than eigen-vector analysis in identifying the best modes for representing structural behavior in response-spectrum and modal time-history load scenarios.
•  Create
  • Make the most of CSiBridge’s interactive design features to increase productivity.

  • Bridges of Composite Steel I- and U-Girder
    • Strength, service, web fatigue, and constructability may all be taken into consideration when designing steel I-girder and U-girder composite slab bridges. One may examine the design demands’ outcomes visually, in tables, and in a comprehensive report.
  • Girder bridges made of concrete boxes and multicell concrete boxes
    • Code tests for primary stress, flexure, shear, and stress are included in concrete box designs. Designs for stress, flexure, and shear are included in Multicell. One may examine the design demands’ outcomes visually, in tables, and in a comprehensive report.
  • T-Beam Structures
    • • Shear, stress, and flexure code checks are included in T-beam bridge designs. The resistance estimates might take prestretched and reinforcing steel into account. A comprehensive report, tables, or graphics may be used to examine the outcomes of the design requirements.
  • Slab Bridges Made of Concrete
    • The design of concrete slab bridges involves code tests for flexure, shear, and stress. Prestressed and reinforced bridges are possible.
  • I- and U-Girder Precast Bridges
    • It is possible to design precast I- and U-girder bridges for primary stress, shear, flexure, and stress. When the AASHTO code is used, the shear resistance is calculated using the Modified Compression Field Theory.
• Loading Score
  • To increase productivity, make use of CSiBridge’s interactive rating features.
    • Rating choices for concrete box girder bridges, multicell box girder bridges, concrete slab bridges, concrete T-beam, steel I-girder, and steel U-girder with composite slab bridges are all completely integrated with the analytical process.
  • Bridges of Composite Steel I- and U-Girder
    • Bridges with composite slabs that use steel I- and U-girders may be assessed for strength and service. One may examine the design demands’ outcomes visually, in tables, and in a comprehensive report.
  • Multicell and Concrete Box Bridges
    • Strength and service ratings are available for concrete box and multicell concrete box girder bridges. One may examine the rating requests’ outcomes visually, in tables, and in a comprehensive report.
  • I- and U-Girder Precast Bridges
    • Strength and service ratings are available for precast I- and U-girder bridges. You may utilize Live Load Distribution (LLD) factors or the individual girder needs straight from the CSiBridge model.
  • T-Beam Structures
    • It is possible to rate the strength and service conditions of T-Beam bridges. The resistance estimates might take prestretched and reinforcing steel into account. One may examine the rating requests’ outcomes visually, in tables, and in a comprehensive report. The related Bridge Superstructure Design handbook provides a thorough explanation of the resistance calculation. The evaluation of resistance is limited to bending at the third horizontal axis. For both positive and negative moments, distinct resistances are computed.
  • Slab Bridges Made of Concrete
    • The section is always handled as a single beam in CSiBridge when allocating loads for concrete slab flexure and shear ratings; all load demands are dispersed equally throughout the whole slab section. When using an area model, the stresses are read from the area elements for the purpose of stress check. When the spine model is used, the stresses are computed using beam theory, with the assumption that the loads are successfully resisted over the slab width.
• Display and Output
  • Distorted geometry
    • It is possible to show mode animations in addition to deformed geometry depending on any load or combination of loads.
  • Force Schematics
    • Internal shear forces, moments, and displacements for any load scenario or combination of loads are shown at every point along the length of a frame member in shear and moment diagrams. CSiBridge allows you to either scroll straight to the maximum value position or along the length to show values.
  • Impact Surfaces
    • A curve of influence values drawn at the load locations along a traffic lane might be thought of as an influence surface. The influence value displayed at a load point for a particular reaction quantity (force, displacement, or stress) at a specific position in the structure is the value of that response quantity attributable to a unit-concentrated downward force operating at that load point.
  • Bridge Reactions
    • Moving load response is computed for each joint and element in CSiBridge. Joint displacements, joint reactions, frame forces and moments, shell stresses, shell resultant forces and moments, plane stresses, solid stresses, and link/support forces and deformations are some examples of the elements for which you can request a group of values for which the response needs to be calculated for each example of response type.
  • Animations
    • To visually represent the behavior of the bridge, CSiBridge enables the animation of the effects of cars and other loads on the bridge model. Movie files with numerous cars and time-history and moving-vehicle replies may be made.
  • Ten: Export and Import
    • Engineers and developers may use the CSI Application Programming Interface (API) to programmatically leverage the power and productivity of CSI software.
    • Using the CSI Platform as a base, create unique solutions to automate processes and boost productivity.
  • Cross-Product Innovation
    • There is presently support for ETABS, SAP2000, and CSiBridge using the CSI API. The CSI API has been designed to be as uniform as feasible across the products to optimize your development efforts. This allows tools and applications developed using one CSI API to be readily modified for use with all CSI products. ETABS v18, SAP2000 v21, and CSiBridge v21 are the first three versions of the software that may be used to create cross-product API tools. As a result, you may develop the code just once and have it used by all three products. Additionally, these API versions don’t need recompiling in order to be forward-compatible with next major versions of these products.
