Abstract：
Compared to has obvious damping measures is a kind of effective seismic defense strategy, the isolation technology changes the traditional structure of hard fight for flexible shockproof effect. First of all, the isolation structure working principle are briefly introduced. Secondly, combined with a vertical irregular office building structure is established to analyze the model, frequent and rare earthquake of elastic plastic time history analysis, combined with the seismic effect of the lower shear, the interlayer displacement angle, acceleration and other indicators were analyzed. The results show that the isolation structure and traditional structure has a good seismic performance, can effectively achieve the stated design goals.
