摘要:
通过离散弹簧模型模拟层间隔震结构的土-结构相互作用(SSI效应),建立了层间隔震结构考虑SSI效应的简化4自由度体系(4-DOF)的结构动力方程,推导了由4自由度体系(4-DOF)向等效2自由度体系(2-DOF)的等效方程。基于等效2-DOF简化计算模型,给出了考虑SSI效应的层间隔震结构地震响应预测的计算流程,并通过一个算例对两种简化模型进行了对比验证分析。结果表明:对层间隔震结构进行考虑SSI效应的地震响应预测分析时,基于等效2-DOF的简化计算模型可替代常用的4-DOF模型,方法简单有效且精度符合要求。
Abstract:
Dynamic equation of simplified 4 freedom system (4-DOF) related to inter-story isolated structure is built based on SSI effect. The transformation equation of 4-DOF transformed to equivalent 2 freedom system (2-DOF) is derived. Based on 2-DOF simplified calculation model,the calculation process is put forward, which is used to predict the seismic response of inter-story isolated structure that should be taken account into SSI effect. By taken a project as study case, two simplified models are verified by time-history method. The result shows that, the2-DOF simplified calculation method has matched the requirements, and can replace the 4-DOF system, a frequently-used method.
