- Tendons in frame, shell, solid elements
- Creep, shrinkage, relaxation, anchorage slip, elastic
shortening and friction losses
- Prestress tendons can be represented as loads or elements for
analysis
- Explicitly model time-dependent effects using tendons
represented as elements
Bridge Layout Definition:
- Quick Definition of Highway Layout
- Layout line definition for bridge components and lanes using
bearings and stations
- Layout line has horizontal and vertical curves and transitions
- Super-elevation definitions
Bridge Model Generation Wizard :
