基于Simulink的桩-土-结构相互作用反应谱分析
|
摘要
在Simulink环境下对桩-土-结构相互作用系统进行了仿真计算分析,并利用反应谱理论研究了SSI效应对上部结构动力响应的影响。采用集中参数模型考虑桩-土对上部结构的影响,上部结构简化为单质点模型,给出了桩-土-结构系统的状态方程,根据模型状态方程在Simulink环境下建立系统的仿真模型,得到了不同场地条件下SSI效应对上部结构加速度谱与位移谱的影响规律。计算结果表明:位移谱基本保持着"刚性假定<Ⅰ类场地<Ⅱ类场地<Ⅲ、Ⅳ类场地"的规律;加速度谱受场地影响的规律不太明显,但在场地较软、桩基刚度较大时,加速度比刚性假定下的要小,而在其他情况下,加速度则比刚性假定下的要大。
A seismic simulation of pile-soil-structure interaction system was done in Simulink environment.The influence of soil-structure interaction(SSI) on dynamic response of superstructure was studied using response spectrum theory.The influence of pile-soil was considered using lumped parameter model.The superstructure was simplified as a single degree of freedom,the state equation of pile-soil-structure system was provided.Simulation model of the system was built under Simulink environment.Influence rules of acceleration spectrum and displacement response spectrum considering SSI under different site conditions was obtained.The results indicate that displacement response spectrum keeps the rule of 'rigid foundation hypotheses
