文摘
- •
A new systematic methodology for seismic collapse risk assessment is proposed.
- •
Failure modes are identified via pushover analyses considering random variables.
- •
A Bayesian network is created to integrate failure modes and uncertainties via IDA.
- •
Sensitivity analysis and estimation of failure modes contributions are presented.
- •
This method enables updating PDFs of random variables based on arriving information.
