摘要
本文在高阻尼橡胶垫单向双折线非线性假设的基础上,运用塑性流动法则,建立了平扭耦联隔震体系隔震层的双向非线性弹塑性本构关系计算模型及其动力计算方程。同时,通过隔震层模型的计算,分析了隔震垫非线性及不同隔震垫布置对隔震层动力性能的影响。本文为考虑隔震层双向非线性的平扭耦联隔震体系设计计算方法的研究奠定了基础。
On the assumption of unidirectional bi-linearity for high damping rubber beating and by use of plastic flow law, the bidirectional nonlinear elasto-plastic constitutive model of the isolation system with coupled horizontal and torsional motion and its dynamic calculation method are established. The influence of the nonlinearity and arrangement of the isolation rubber beating on the dynamic characteristics of the system are analyzed. The results lay a foundation for further research on the design method of translation-torsion coupling isolated system.
