According to the code for aseismatic design of building structure ( gbj11 - 89 ) , the seismic base - shear method has always been used to calculate the seismic response of building structures . in those structures , their weights and rigidities equally distribute along their heights which do not exceed 40m , and their deformations are mostly the shearing type ( when the structures " ratio of height and width are smaller than 4 ) 我国《建筑抗震设计规范》 ( gbj11 ? 89 )中规定,对于重量和刚度沿高度分布比较均匀、高度不超过40m ,并以剪切变形为主(房屋高宽比小于4时)的结构,可采用近似计算法,即底部剪力法来计算其地震响应。
