Analyze and Design

This section explains how to run structural analysis and design verification for the Steel Tub Girder Bridge.

Navigation: Analyze and Design

Overview

OpenBrIM computes parametric equations to create 3D/FEA/CAD representations based on project inputs. The process includes:

• FEA Model Generation: Node merging, meshing, load generation, influence surface coefficients
• Analysis: Time-dependent staged construction analysis
• Design: AASHTO code compliance verification with DC ratio calculations

After parameter changes, you can rerun analysis or use previous results if the change doesn't affect the FEA model.

Steps

Step 1: Run Analysis

Click the Analyze icon and select Run Analysis.
