Abstract

In the milieu of rapid urbanization, prefabricated frame structures, owing to their superior construction efficiency and quality control benefits, have garnered extensive application within the realm of architecture. Nonetheless, in regions prone to frequent seismic activity, the safety performance of such structures has ascended to the forefront of engineering and scholarly inquiry. To study the vulnerability and collapse resistance of pre-fabricated frame structures with seismic systems, this paper takes a typical multistory reinforced concrete frame structure as the analytical model in an 8 degrees, 0.2g seismic region. The PKPM software was utilized to design the seismic system model of the prefabricated frame structure. 23 commonly used natural earthquake waves were selected as dynamic inputs, and the IDA analysis method was employed. The ETABS finite element analysis software was used to conduct vulnerability analysis on the prefabricated frame structure’s seismic system, while the collapse resistance of the seismic system was evaluated using the CMR method. The research shows that the seismic system of the prefabricated seismic frame structure exceeds a probability of more than 50% under four performance levels, with corresponding PGAs of 0.13g, 0.31g, 0.54g, and 1.01g respectively. The corresponding safety reserve factors under rare earthquakes are 2.53, which are close to the recommended safety reserve factors. Furthermore, the collapse resistance reserve factor under extremely rare earthquakes is 1.8, indicating that the prefabricated frame structure’s seismic system has a good resistance to collapse.
