为比较在同时考虑两个水平方向地震影响的情况下，多层框架抗震结构和橡胶垫减震结构变形的区别，采用空间杆系模型在弹塑性范围内对结构进行了动力分析·介绍了进行动力分析的方法，计算了两种结构在地震波作用下各层的层间位移等地震反应·从动力反应的比较可见，减震结构采用橡胶隔震垫后，改善了结构的动力特性，从而使整个上部结构的地震反应大大降低；在同时考虑两个水平方向地震作用时更能体现出减震结构相对抗震结构的优越性·
In order to compare the effects of earthquakes in two horizontal directions, the difference between the deformation of the multi-story frame seismic structure and the damping structure of the rubber cushion, the dynamic analysis of the structure using the space bar model in the elastic-plastic range was introduced. The dynamic analysis method calculates the seismic response between layers of the two structures under the action of the seismic wave. From the comparison of the dynamic responses, it can be seen that after the shock absorbing structure adopts the rubber insulation pad, the dynamic characteristics of the structure are improved. The seismic response of the entire superstructure is greatly reduced; the superiority of the shock-absorbing structure relative to the seismic structure can be better reflected when considering the simultaneous action of two horizontal earthquakes.
