Study on Seismic Vulnerability of High-rise Shear Wall Structure Based on IDA Method
In this paper,taking an existing high-rise shear wall building structure as an example,the phenomenon of private shear wall demolition is simulated by cutting part of the shear wall as vari-ables,and the impact of dismantling the shear wall on the overall seismic performance of the struc-ture is judged through data comparison.On the basis of incremental dynamic analysis and com-bined with the vulnerability study,by adjusting the seismic wave PGA,the maximum inter-layer displacement Angle under different intensity was obtained,and the seismic performance level and damage level of the structure were divided to determine the surpassing probability model at each performance level.The study shows that the removal of part of the shear wall affects the overall seismic performance of the structure,and improves the probability of the structure exceeding the limit state.Among them,the seismic performance of the shear wall on the 10 floors is the worst.The seismic performance of the shear wall on the 1 floor is comparable to that of the shear wall on the 19 floors,and the seismic performance of the base structure is optimal.
