随着近年来地震工程的发展,基础隔震结构的应用越来越广泛,而铅芯隔震橡胶支座以其突出的优点更是运用十分广泛。铅芯隔震橡胶支座的力学模型通常采用双线性力学模型进行模拟,而实际上支座发生大变形时,其滞回曲线呈现三线性的形态,本文就此提出确定三线性力学模型参数的计算方法,并通过ANSYS分析软件对采用不同力学模型进行的建筑隔震分析结果做了对比,对比研究表明多遇地震下分析结果相差很小,罕遇地震下分析结果差别较大。

With the development of earthquake engineering in recently years, the application of base isolation structure is more and more widely. Because of the prominent advantage of lead- rubber isolation bearings, it is widely used in this range. The mechanical model of lead- rubber isolation bearings usually use bilinear hysteretic model, but the actual hysteretic behaviors under major earthquake presents tri-linear perform. So it is necessary to consider the impact of differences of the large deformation bearing mechanics model for isolation analysis. In order to correctly utilize the analysis model, basing on the theory study, the mechanical parameters of the tri-linear model of isolation bearing was studied. The different dynamic response of two kind of isolated structures which is used bilinear model and tri-linear model of lead rubber bearings was also discussed.文章源自建筑隔震支座_隔震橡胶支座_密封件_厂家定制批发-http://www.go-we.com/1125.html
