Abstract:
In order to study the reliability of anti-progressive collapse of structures under accidental loads, the numerical model of steel frame progressive collapse analysis was established by OpenSees software. Considering the uncertainty of materials and loads of steel frames, Latin hypercube sampling method was used to generate random samples of steel frames, and random Pushover algorithm was used to analyze steel frames. The reliability indexes of load capacity and deformation capacity of each steel column under different seismic action levels in X and Y directions were calculated, and the target reliability indexes were determined according to the seismic reliability theory. By comparing the reliability indexes and target reliability of each column, the most probable failure members of the structure under seismic action were identified. Based on the identified most probable failure members and 100 groups of steel frame structure random samples, IDA analysis of steel frame structures under various working conditions such as single-column failure and multi-column failure was carried out by the alternative path method, and the random IDA analysis curves were obtained. Through the limit state equation of progressive collapse,the probability of progressive collapse of damaged structures and the conditional reliability index of progressive collapse were calculated. The full probability reliability of progressive collapse of steel frame structure after local damage under seismic action was analyzed through the probability expression of structure progressive collapse at risk, which can provide a basis for accurately evaluating the anti-progressive collapse ability of steel frame structure under seismic action.
