Axis Based Modelling of a Concrete Composite Bridge

Axis Based Modelling of a Concrete Composite Bridge

Course modified date: 15 August 2026

Learn how to create an axis-based bridge model using Computer Aided Bridge Design (CABD).

You define girder and deck slab axes, create secondary axes, place diaphragms, establish geometric references, and control rotations for curved bridge layouts. The content demonstrates deck slab generation between placements, cantilever adjustments, diaphragm alignment, and reference management for adaptive geometry.

You also create load actions, load cases, line loads, area loads, crash barrier loads, and prestressing load cases. Finally, you verify how loads and geometry automatically follow alignment changes, enabling efficient modelling of straight and curved composite bridge structures.
