Modeling Of Bridge Systems
CSiBridge Implements A Parametric Object-Based Modeling Approach When Developing Analytical Bridge Systems. This Enables Designers To Assign Bridge Composition As An Assembly Of Objects (Roadway Superstructure, Substructure, Abutments, Piers, Foundation System, Etc.) Before The SAPFire ® Analysis Engine, Integral To CSI Software, Automatically Transfers The Object-Based Model Into A Mathematical Finite-Element Model By Meshing The Material Domain And Assigning Material Properties. This Object-Oriented Approach Simplifies And Expedites The Modeling Process, Saving Engineers The Need To Directly Define, Link, Constrain, And Mesh All Material Volumes.
CSiBridge Also Allows Engineers To Import Model Data From Dwg/Dxf, IGES, CIS/2 STEP, And Land XML File Formats, Or Export To PERFORM-3D, MS Access, And CIS/2 STEP, All Following IFC Standards.
Loading And Analysis
After Modeling, CSiBridge Provides Options For The Assignment Of Load Cases And Combinations. Vehicle, Seismic, And Wind Loading Are Generated According To Building Code (AASHTO LRFD, Canadian, Etc.) And Assigned According To Model Geometry. A Series Of Templates For Assigning And Enveloping Load Conditions Make CSiBridge Intuitive And Practical.
Analysis Capabilities Go Well Beyond Elastic Performance Into The Assessment Of Inelastic Behaviors. Geometric And Material Nonlinearities Provide Insight Into Strength, Ductility, And Other Performance Measures Critical To Response Under Extreme Loading. Static-Pushover And Dynamic Analyses (Steady-State, Response-Spectrum, And Time-History) Provide Further Insight Into Earthquake Resilience. Substructure Hinging Properties Are Customizable.
Additional Analysis Features May Account For Creep And Shrinkage Behavior, Post-Tensioning With Optional Automatic Cable Tensioning, Staged-Construction Effects Inherent To Segmental Construction, Buckling, Camber And Shape Finding.
Design And Output
Customizable Reports Present Analysis And Design Details In A Variety Of Formats. Moment, Shear, And Axial Response Data And Diagrams In 2D And 3D Views, Seismic-Displacement Capacity, Demand-Capacity Ratio, Load Rating Per Classification, Influence-Surface Plots For Displacement, Reaction, And Frame, Shell, Solid, Or Link Response Are All Options For Output Generation.
