Defining cross-sections, materials, and variations along the span.

Increase iteration limits or provide realistic initial stiffness to boundary links. 8. Best Practices for Professional Engineers

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.

The layout line dictates the horizontal and vertical alignment of the bridge. Go to the tab. Click Layout Lines > Add New Line . csi bridge user manual

Initialize your project, set units, and define design codes (e.g., AASHTO) under the Project node.

Designate column configurations, cap beam geometries, and footing properties.

The most efficient method for standard bridges is using the , which allows for rapid modeling of concrete box girders, tee beams, flat slabs, steel girders, and precast concrete I/U girders. Alternatively, the Segmental Bridge Template provides a more advanced parametric workflow. Once a model is generated via a template, users can refine it using the commands on various tabs or the Bridge Wizard, though it's worth noting that the Bridge Wizard cannot modify "specific purpose" templates like Caltrans BAG or suspension bridges. Best Practices for Professional Engineers Go to the

is the primary technical document. It covers general technical topics fundamental to modeling, analysis, and design for CSiBridge. Core Manuals and Documentation

Go to Components > Abutments . Specify how the end of the bridge deck connects to the foundation (skews, diaphragms, and bearing assignments).

Located under the Home tab, this opens a side window containing detailed information regarding bridge models and components. The layout line dictates the horizontal and vertical

Bridges require flexible boundaries to handle thermal expansion and seismic forces.

Evaluate structures against international design codes (AASHTO, Eurocode, etc.). 2. Setting Up Your Project A successful project begins with proper configuration. Initializing the Model Open CSiBridge and select File > New Model .

Everything begins with the horizontal and vertical alignment. The manual instructs users to define station equations, coordinate systems, and explicit horizontal/vertical curves. This layout line serves as the geometric anchor for the entire structure. Step 2: Bridge Deck Cross Sections
