多层建筑隔震设计及探讨

Seismic Isolation Design and Research of Multi-Storey Building

对多层建筑基础隔震体系的设计过程和关键问题进行探讨,并对隔震体系进行非线性时程分析.计算结果表明,隔震结构的地震加速度响应、位移响应大幅降低,隔震体系的应用提高了结构的抗震承载力,可有效减少上部结构的地震作用.

Seismic isolation design of multi-storey building is performed in this paper.Nonlinear time-history analysis is adopted in the isolator structure design.The calculating result indicated that seismic acceleration and displacement response of isolated structure significantly decreases.Application of base isolation system can ease the reaction and the harm of structure availably under earthquake.
