Bridge Geometry

This section defines the geometric layout of the Concrete U Girder Bridge, including alignments, support locations, and girder configurations.

Navigation: Bridge Geometry

Overview

Bridge Geometry establishes the foundational layout for the entire bridge model. This includes:

• Roadway Alignment: Horizontal and vertical alignment with cross-sections
• Bridge Alignment: Assignment of alignments to bridge structures
• Support Lines: Locations of abutments, piers, and temporary supports
• Insertion Points: Positioning of U-girders along support lines
• Girder Layout: Connection of insertion points to form girder lines

Sections

Section	Description
Roadway Alignment	Define horizontal, vertical, and transverse alignment
Bridge Alignment	Assign roadway alignment to bridges
Support Lines	Define support line stations for abutments, piers, and temporary supports
Insertion Point	Position U-girders along support lines
Girder Layout	Connect insertion points to create girder lines

Complete each section in order to establish the bridge geometry before proceeding to Properties.
