Csi Bridge User Manual [portable] Online

Combines modeling, analysis, and design in a single user interface.

Create a new load case, change the load case type to Moving Load , and assign your lanes and vehicle classes.

Go to the tab and click Bridge Objects > Add New Bridge Object . Assign the layout line to the object. Define the span lengths and assign the deck cross-section.

Let’s dissect the latest version (v25 as of this writing). The manual typically contains 18–20 chapters. Here are the most critical ones: csi bridge user manual

Always run a quick spine (line-element) analysis before building complex shell or solid meshes. This helps catch geometry or boundary condition errors early.

Assign span lengths by adding "Span Items" corresponding to your layout line stations.

Once the analysis is complete, the tab allows you to check the bridge against specific codes. The software generates detailed reports for: Flexure and Shear capacity. Serviceability (crack control and deflection).

Input the horizontal coordinates (station, coordinates, and bearings) and vertical alignment data (grades and vertical curves). Step 3: Define Material and Section Properties Go to the tab.

If your bridge deck changes width or depth along its length, use the Parametric Variations tool. This avoids having to create dozens of individual cross-sections. Assign the layout line to the object

The official CSiBridge software includes extensive built-in documentation to guide users.

The manual details several core functionalities designed for complex engineering:
