框架结构-桩筏基础-地基共同作用时程分析

Time-procedure analysis of interaction of frame structure-piled raft foundation-soil

利用有限元软件ANSYS 10.0建立传统模型和框架结构-桩筏基础-地基的共同作用模型。采用时程分析法,在一定条件下对地震作用下的传统模型和共同作用模型进行数值模拟分析。结果表明,共同作用模型的最大层位移有所增大,但层间位移有所减小,说明在一定情况下考虑共同作用对结构整体上是有利的。

A traditional model and an interaction model of frame structure-piled raft foundation-soil are established by using the FEA software ANSYS 10.0.Time history method is used to simulate and analyze the traditional model and interaction model under certain conditions.The results show that under seismic effect,the maximum story displacement of the interaction model increases,but the inter displacement decreases,which indicates that considering the interaction in a certain case is beneficial to the structure as a whole.
