抗震性能包括对结构低阶自振周期、顶点位移、最大层间位移角、框架承担承担水平地震剪力、框架承担地震倾覆力矩比几个方面。
The main seismic performance is introduced, including low level period, top displacement, maximum layer displacement Angle, frame bearing horizontal shear, frame bearing earthquake overthrow moment.
因此，对橡胶支座的水平刚度和抗震性能进行深入细致的研究有着非常重要的理论意义和工程实用价值。
Therefore to conduct a deep study on horizontal stiffness and hysteretic performance of rubber bearings has a very important theoretical significance and practical value.
然而，由于地震作用的随机性与多维性，仅仅对钢筋混凝土箱型柱进行正向水平荷载作用下的抗震性能研究往往是不够的。
However, Because of the randomness and multidimensional of earthquake, the only study of the seismic performance of RC box columns under unilateral loading is often not enough.
