文摘
- •
A probabilistic dynamic progressive collapse analysis method is proposed.
- •
Reliability analysis models of a truss bridge and a box-girder bridge are presented.
- •
The reliability analysis is performed to evaluate the redundancy of two bridges.
- •
The effect of different damage scenarios on structural safety is evaluated.
- •
The reliability analysis results can be used to calibrate incremental analysis.
- •
The method can be implemented to cover a wide range of bridges and damage scenarios.
- •
The method can be used to develop progressive collapse bridge design guidelines.
