Abstract
Abstract The seismic response of a typical vertical light industrial building structure is complex, and once damage occurs, it will cause great disasters and losses, so it is very important to evaluate the seismic performance of vertical light industrial building structures. This paper firstly analyzes the IDA principle and determines the ground shaking strength index and structural damage index based on the IDA curve. Secondly, the structural vulnerability curve and the model are derived based on typical vertical light industrial structures, and the structural characteristics of typical vertical light industrial buildings are analyzed. Finally, the seismic performance of the building structure is evaluated and analyzed based on the IDA method, and the seismic vulnerability analysis is carried out for vertical light industrial buildings with different concrete structures. The PA values of CFST structures in four limit states are 0.81g, 0.21g, 0.34g and 0.47g, which are slightly higher than those of RC structures and have better seismic performance.
