Csi Bridge User Manual Free Jun 2026

Create a new load case. Set the load case type to Moving Load . Assign your vehicle classes and lanes. Specify whether the analysis should calculate influence lines or use direct step-by-step integration.

For post-tensioned bridges, tendons are defined parametrically. You can specify the vertical and horizontal profiles, prestressing losses (friction, anchor set, elastic shortening, creep, and shrinkage), and jacking forces. 3. Step-by-Step Modeling Workflow

: An in-software tool that provides step-by-step instructions for creating a complete bridge model, ensuring all necessary components are defined. csi bridge user manual

The reference manual outlines sophisticated analysis options essential for modern bridge engineering:

Go to Home > Deformed Shape and select a load case to check for expected deflection patterns. Force Diagrams: Go to Home > Force Diagrams to view Shear ( V2cap V sub 2 V3cap V sub 3 ), Bending Moment ( M2cap M sub 2 M3cap M sub 3 ), and Torsion ( Create a new load case

What you are running (e.g., static, staged construction, seismic).

CSiBridge integrates the entire design process into a single, intuitive user interface. It utilizes a parametric object-based modeling approach, allowing engineers to define a bridge using its physical components rather than abstract mathematical lines and nodes. Key Capabilities live load distribution

: A searchable online portal with technical papers, FAQs, and test problems for CSiBridge .

Bridges require foundations and supports to transfer loads to the ground.

Set up load cases, moving loads, and staged construction sequences.

CSI Bridge is a structural analysis and design software developed by Computers and Structures, Inc. (CSI). Unlike general-purpose finite element (FE) packages, CSI Bridge is tailored specifically for the modeling, analysis, and design of bridge structures. It combines the robust analytical power of the SAPFire analysis engine with a suite of bridge-specific tools that automate complex tasks such as deck geometry definition, live load distribution, and code-based design checks.
