摘要
减震措施是一种有效的地震防御策略,隔震技术变传统结构硬抗为柔性防震,具有明显的效果。介绍隔震结构的工作原理,结合某立面不规则的办公楼结构建立分析模型,进行多遇和罕遇地震下的弹塑性时程分析,分析各烈度地震作用下层剪力、层间位移角、层加速度等指标,结果表明隔震结构具有良好的抗震性能,能有效实现既定设防目标。
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.
