土-基础-高层框架结构振动台试验及有限元分析

Shaking table test and finite element analysis of soil-foundation-frame structure

文章基于分层土-支盘桩-高层框架结构相互作用体系的振动台试验,对结构在地震作用下的动力特性与反应进行分析;应用SAP2000分析程序对模型结构进行动力计算,将试验和数值模拟2种结果进行比较,验证数值模拟的可行性;通过软件分析获取结构在地震荷载的作用下,上部结构中梁、柱、板的内力反应,并对结构纵横双向不等跨的不同反应作出对比,找出结构的薄弱部位,对框架结构的设计提出若干建议。

Based on the shaking table tests on interaction system of layered soil-branch piles-high rise frame structure,the analysis of dynamic performance and responses of the structure under earthquake is given in this paper.The dynamic calculation of the model structures is also made with the analysis programs SAP 2000,and the numerical results are compared with the test ones to verify the feasibility of numerical simulation.The interior responses of the beam,column and slab in upper structure under earthquake load are obtained,and the weak areas of the structure are found out,and some advices are put forward for the design of frame structure.
