梁式与桁架式高位转换层对整体结构的影响

The Influence of the Whole Structure with Beam Transfer and Truss Transfer Layers at a Higher Level

带高位转换层的建筑结构是一种竖向不规则的复杂建筑结构,由于此种结构的构造和施工复杂,实际工程的应用并不是很多,研究也较少。本文采用SATWE有限元分析软件,通过反应谱分析方法,研究了桁架和梁式转换层在整体结构中的动力特性。然后对比结构的周期、振型、位移和层间剪力等方面的差异,研究这两种形式的高位转换层对整体结构的影响。

The structure with transfer layer at a higher level is one kind of vertieally irregular and complicated style so that its seismic mechanism is not specific. Because the structure and construction are complex, there are few actual structures and research. This paper used the finite element software-SATWE, through the response spectrum analysis, analysed the dynamic characteristics of truss transfer layer and beam transfer layer at a higher level. The differences of the cycle and vibration mode, layer drift, layer shear and other aspects of the performance of the structure are compared, in order to research the influence of the whole structure with different transfer layers at a higher level.
