摘要
本文介绍了某超高层型钢混凝土框筒结构体系整体结构模拟地震振动台试验模型材料的选取,动力相似关系的确定以及模型设计。对模型结构在7度多遇地震、基本地震、罕遇地震和8度罕遇地震阶段的动力特性,加速度及位移反应进行了试验分析。同时,应用结构有限元分析程序对模型结构进行动力计算,将两种结果进行比较。最后给出结构的薄弱部位,并对结构设计提出了建议。
In this paper,the shaking table test on a super high-rise steel reinforced concrete frame-core wall building structure is introduced,which includes the structural system characteristics,model material selection, similitude relationship and simplified design of the model structure.The dynamic property,acceleration and displacement responses of the model structure are analyzed.The dynamic calculations of the model are also made using structural finite element analysis programs and the results are compared with those of the test.Finally, the weak floors of the structure are found out and some advices are put forward for the design updating.
