Simulation analysis on continuous collapse resistance of assembled building structure under multi-dimensional earthquake

Under the multi-dimensional earthquake, the random damage of the building column structure is large, and the analysis of the continuous anti collapse performance of the building structure is limited. Therefore, the simulation analysis of continuous anti collapse of assembled building structure under multi-dimensional earthquake is proposed. Through the analysis of the undamaged structure of the building, it is found that under the action of multi-dimensional earthquake, if the long side column, corner column and inner column of the building structure are damaged, it may lead to the collapse of the assembled building structure. The test results show that the continuous collapse caused by inner column demolition is the strongest, followed by long central column, corner column demolition will not cause the continuous collapse of the building structure.
