Research on Seismic Vibration Table Simulation of Large LNG Storage Tanks Based on Numerical Simulation
摘要
In order to study the dynamic characteristics and seismic performance of a large LNG storage tank, a finite element analysis model of the shaking table test model of a large LNG storage tank was established by using finite element calculation software with the background of 160,000 m3 LNG storage tank. The seismic response of the model structure was studied from the three directions of acceleration amplification factor, relative displacement and strain, and the seismic performance of the storage tank model under different seismic waves was obtained. The research results are of great significance for the study of dynamic characteristics and overall seismic performance of large LNG storage tanks.
