摘要
首先分析了隔震单元的本构模型,在此基础上利用大型有限元分析软件SAP2000对一栋采用橡胶垫支座隔震的8层框架结构在抗震和隔震两种情况下进行了模态分析,通过对比分析得出隔震结构减震效果非常明显,结构施工并不复杂。
This paper first analyzes the constitutive relation model of isolation unit. Based on this, a model analysis of 8 floor frame structure with support of earthquake-resistant building and base-isolation building is given by SAP2000 finite element software. Throgh comparison analysis, it gets the conclusion that the effect of quakeproof structure is obvious, and the structure construction is not complex.
