Assign abutments, bents, and bearings to specific station locations.

The Bridge Object brings your layout, cross-sections, and substructure together. Navigate to the tab and create a new Bridge Object. Assign the defined layout line.

Tailored functionality for concrete and steel bridges, including concrete box girders, steel girders, and cable-stayed structures. 2. Getting Started: The CSiBridge Interface

Choose standard code vehicles (e.g., HL-93 for AASHTO LRFD, LM1/LM2 for Eurocode) or customize axle weights and spacings.

Once the analysis is complete, CSiBridge performs comprehensive code checking according to international standards, including AASHTO LRFD, Eurocodes, Canadian CSA codes, and British Standards. Running the Design Check Go to the tab.

: A specialized manual for new users that introduces design workflows for concrete box girder and precast concrete girder bridges. Release Notes

Click to select standard design vehicles (e.g., HL-93, HL-93 Truck, Design Tandem, Eurocode LM1).

The "Bridge Wizard" is often the first chapter for new users. The manual details how to use this step-by-step tool to define: Horizontal and vertical alignments.

Define translational and rotational stiffness (fixed, expansion, or elastomeric).

This guide serves as a practical manual to help structural engineers navigate the core components, workflows, and advanced capabilities of CSiBridge. 1. Introduction to CSiBridge and the Parametric Workflow

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

For bridges built in phases (e.g., segmental or precast), the manual contains specific test problem documentation. The "Staged-construction analysis of two-span precast-girder bridge" tutorial illustrates how to set up construction stage analysis. The manual highlights the key logic: defining property modifiers to simulate "wet concrete" (with weight but no stiffness) versus "hardened concrete" (with full stiffness) to accurately model the time-dependent behavior of the structure.
