摘要
用ANSYS软件作为桩-土-结动力相互作用分析的工具,建立了中震及大震下钢筋混凝土剪切型结构考虑桩-土-结动力相互作用效应的非线性模型,进行了中震及大震下桩-土-结相互作用体系的非线性地震反应时程分析,研究了土-结动力相互作用效应对结构地震反应的影响。结果表明地震动作用过程中,桩与土体之间交替地处于接触、滑移和脱离状态,对结构的地震反应有一定的影响。
In this paper, by using ANSYS software, a simplified nonlinear PSSI computation model is established for shear - type RC frame structures under moderate and rare seismic. The nonlinear of soil and piles present in and the nonlinear seismic time - history analysis is performed for PSSI system under moderate and rare earthquake, and parametric influence of system is studied. It shows that the contact state between the pile and the soil changes from contact and slippage to separation with seismic load, and separation influences the seismic response of structure.
