Vulnerability Analysis Based on Ground Motion Intensity Parameters

Abstract Based on the ground motion intensity parameters PGA and Sa, this paper conducts a comparative analysis of the vulnerability of the Guangyue building’s wooden structure. The results show that under the same earthquake intensity, the existence of a high platform will increase the probability of damage to the Guangyue building’s wooden structure; PGA is used as an earthquake When evaluating dynamic strength parameters, the probability of evaluating the structure to reach each limit state is large, that is, the possibility of the structure exceeding various limit states is large, and the result is conservative, which is more conducive to ensuring the safety of the structure.
