摘　　要：地震作用下,我们在进行两个质点的仓体的内力计算时,通常只会考虑两个方向的自由度,往往忽略掉仓体的转动对仓体的影响,本文利用MATLAB计算软件对筒体的仓顶室进行层间剪力的计算,通过是否考虑仓体的转动,对比得出在进行仓体内力计算数值的影响程度,从而得到考虑筒体转动与否的必要性。When calculating the internal force of the silo body with two particles under earthquake action,we usually only consider the degree of the freedom in two directions while neglecting the effect of silo rotation on the silo body.In this paper,MATLAB was used to calculate inter-laminar shear of top room of the silo,through consideration and non-consideration of the silo rotation and their comparison,the degree of influence of silo rotation was derived in calculation of internal force of silo,and the necessity for whether to rotate the silo was given.
