球罐地震反应分析及其子结构拟动力试验方法
Seismic response analysis and the sub-structure pseudo-dynamic test of spherical tank
摘要
Abstract
In order to investigate the effect of fluid-structure coupling on the seismic response of the spherical tank,the finite element model of 1 000 m3 spherical tank is established by ABAQUS software.The modal analysis of spherical tank is carried out by using the subspace method,and compared with the canonical algorithm.At the same time,the coupled Lagrange Euler algorithm is used to analyze the seismic response of the spherical tank considering fluid-structure coupling.The results show that the attenuation of the top displacement,the base shear force,the vertical force,and bar stress are more rapid and the numerical results are much smaller than those of the additional mass method.On this basis,the sub-structure pseudo-dynamic test method is introduced,and the sub-structure pseudo-dynamic test method is proposed to analyze the seismic performance of spherical tank.The sub-structure pseudo-dynamic test method of spherical tank structure is presented,which provides a new experimental method for the study of spherical tank.关键词
