Parametric Bridge Design
with Rhino/Grasshopper & SOFiSTiK

In this recording, we will show you how to create a parametric analytical model of a balanced cantilever bridge in Grasshopper. Attach cross-sections, placements, and any further relevant information to the road alignment and build a fully parametric bridge model for analysis and design.

Benefit from the streamlined workflow between Grasshopper and SOFiSTiK to maximize efficiency, flexibility, and accuracy.

What you will learn

• Organize input data in a spreadsheet and create the bridge superstructure along an axis with a master cross-section, variables, and placements.
• Define the superstructure as a spine model. Assign construction stage numbers and section Id’s to the structural lines.
• Specify support conditions using placement names or station values.
• Define cantilever and continuous tendons based on placement names or station values.
• Modify the model and visualize its data in Rhino.
• Apply permanent and variable loads.
• Perform a construction staged analysis.
