【摘要】 对带转换层的错层高层结构抗震性能进行了振动台试验研究和有限元计算分析,测试了模型结构的动力性能和结构地震反应。为对比错层结构和传统结构的抗震性能,采用三维SAP2000有限元程序建立并分析了该试验结构模型和对应的传统结构模型,两分析模型的结构参数和质量分布相同,仅楼板位置不同。对比分析的试验与计算内容包括:模型结构周期、振型、加速度反应、位移反应和层间位移角反应。分析结果表明,模型结构试验结果与计算结果沿高度分布规律基本一致;因地震波特性不同,错层结构与传统结构反应存在一定差别。更多还原

【Abstract】 Recently,many special and complicated high-rise buildings have been constructed in engineering.For seismic design requirement,it is important to confirm the safety of the buildings under earthquake.In this paper,the seismic performance of a complicated high-rise building with staggered floor and transfer floor by experimental and finite element analytical methods are studied.The shaking table tests of the building model are performed in order to examine the dynamic characteristics and seismic responses of the structure.To compare the seismic behaviors of the stagger structure with the traditional structure,the tested model of the stagger structure and the traditional model are developed and analyzed by FEM with 3D SAP2000 program.The structure elements and mass distributing of the two analytical models are the same,only the floor location is different.The compare results content the structure periods,modes,acceleration responses,displacement responses and inter story drift angle response between test results and calculation results.Results from the test and calculation show that the results along the height between the structure model and analytical model are consistent,the results between the stagger structure and the traditional structure are different from the acting waves.更多还原
