Dynamic Characteristics And Seismic Response Of High-rise Building Of Frame-shear Wall Structure With High Transfer Story

With the development of economic and social, the function of high-risebuilding structure trends to be a wide range of use. High-rise building of CFSTframe-shear wall structures with transfer story located high position is widely used.Relevant design and calculating provisions on such a structure beyond the Chinesecode limits. In this paper, by numerical modeling to study the seismic performanceof the high transfer frame-shear wall high-rise buildings in use of the finiteelement analysis software SAP2000to provide some practical references to designand theoritical analysis of such a structure. The main contents are as follows:1. Some details of the principle of finite element analysis and methods thathow to model the finite element of such specific engineering structures, and theprocessing characteristics of concrete filled steel tubes, especially the selection ofconfined concrete constitutive relationship is given. Preliminary comparisons ofnumerical results with the shaking table test of the model structure are given,integrated to determine the seismic performance.2. By changing the relevant parameters which include the equivalent lateralstiffness ratio, rigid floor assumptions and equalling CFST column as a reinforcedconcrete box pillar in accordance with the same axis pressure bearing capacity, thedynamic characteristics and the seismic performance of the structure is studied inthe elastic state.3. Through elastic-plastic history analysis of the high transfer frame-shearwall high-rise buildings under the severest design ground motions, the regularityconclus ions of seismic behavior and failure mechanism of such structures are given.
