Csi Bridge User Manual Jun 2026

: Official video tutorials available on the CSi America website that cover introductory modeling, moving loads, and advanced design.

Unlike general-purpose finite element analysis (FEA) software, CSiBridge uses an object-based parametric modeling approach. This means you define the bridge using physical components—such as alignments, spans, decks, abutments, piers, and tendons—rather than starting with individual nodes and elements. Key Benefits of Parametric Modeling

These complement the user manual and are legitimate for learning. csi bridge user manual

[Materials] ➔ [Frame/Shell Sections] ➔ [Bridge Deck Sections] ➔ [Substructure/Abutments] Material Properties Go to the tab. Click Material Properties > Add New Material . Specify concrete compressive strength ( fc′f sub c prime ), steel yield strength ( Fycap F sub y ), and modulus of elasticity ( Frame and Shell Sections

To define the bridge deck cross-section, go to and select your deck type (e.g., Concrete Box Girder). Input the detailed parametric dimensions (web thickness, slab depth, overhangs). 3. The Parametric Bridge Modeling Workflow : Official video tutorials available on the CSi

Select your bridge type (e.g., Concrete Box Girder, Steel I-Girder, Precast Concrete U-Girder, Flat Slab).

Bridges are rarely built instantaneously. The feature allows engineers to simulate the construction timeline. Key Benefits of Parametric Modeling These complement the

The Bridge Object binds your alignment, deck section, and substructure together. Go to the tab and create a new Bridge Object.

View bending moment diagrams, shear forces, displacement contours, and stress distributions directly on the 3D model.

Select your desired design code (e.g., AASHTO LRFD 2020) via the menu.
