Steel Tub Girder Bridge Model

Workflow Steps

Step	Section	Description
1	Modeling on OpenBrIM.App	Create new project
2	Bridge Geometry	Define alignment, supports, girder layout
3	Properties	Configure materials, rebars, sections
4	Superstructure	Define tub girders, deck, bracing, connections
5	Substructure	Configure piers and foundations
6	Construction	Set up staged construction sequence
7	Loading	Apply live, wind, temperature loads
8	Superstructure Attachments	Add barriers and roadway
9	Combinations	Configure load combinations
10	Templates for Code Check	Set up design verification templates
11	Superstructure Code Checks	Verify girder and bracing design
12	Substructure Code Checks	Verify pier and foundation design
13	Reports	Generate camber diagrams and quantities
14	Analyze and Design	Run analysis and design checks

Key Capabilities

3D Modeling & Export

• Generate parametric 3D models with substructure and superstructure
• Export to DGN/DXF/IFC formats

Finite Element Analysis
