摘　　要：PKPM-GZ是针对中震下的一体化隔震设计方法进行开发的,为探讨程序在高层建筑隔震计算中的应用精确性,文中对同一高层框架-剪力墙结构,采用PKPM-GZ和ETABS计算对比分析,分析了两套软件隔震前后的楼层剪力、楼层剪力比、楼层位移角、抗倾覆和隔震支座验算。计算结果表明,PKPM-GZ和ETABS计算得到的楼层剪力比最大值分别为0.36和0.34;楼层位移角的最大值均小于规范的限值1/800;支座的极限拉压应力最大误差在20%以内。PKPM-GZ和ETABS软件在高层隔震计算中具有较好的一致性。PKPM-GZ is developed for the integrated seismic isolation design method under the medium earthquake.PKPM-GZ and ETABS are used in the same high-rise frame-shear wall structure,which was isolated and non-isolated.The floor shear force,the ratio of the floor shear force,floor displacement angle,overturning resistance,and seismic isolation bearing test are analyzed.The calculation results show that the maximum values of the ratio of the floor shear force calculated by PKPM-GZ and ETABS are 0.36 and 0.34 respectively,and the maximum values of the floor displacement angle are less than the limit value of 1/800 of the code;the maximum errors of ultimate tensile and compressive stresses of bearings are within 20%.The results from PKPM-GZ and ETABS software have good agreement in seismic isolation calculation of high rise structures.
