西安建筑科技大学硕士学位论文 西安建筑科技大学硕士学位论文 Complex high-rise building with transfer plate structure seismic performance research Specially：Structure Engineering Name：Wang Guangdong Instructor：Associate Prof. Zhao Xindong Abstract Transfer plate structure in the domestic application is increasing, but the theoretical research of no transfer beam structure maturity, mechanism research is not thorough, and for conversion of the Twin Towers plate structure, in-depth research is rare. Under horizontal earthquake action, seismic performance of structure transfer plate in Twin Towers, need thorough research. In this paper, in order to establish the model as research object, on the Twin Towers with a slab conversion layer structure was studied, the main contents include: Application of high-rise building by finite element method and the theory of dynamic structure analysis, using ANSYS software to establish the structural analysis model. A transfer plate structure modal analysis, draw the structure of first twenty vibration shape and frequency, the vibration regularity of vibration characteristics. The results show that, for the band of thick plate transition Twin Towers structure, high order mode on structure influence. Based on the modal analysis of the premise, choosing earthquake wave data, the model for the response spectrum analysis, according to the calculation results of seismic performance curve drawing. Considering the plate thickness, tower stiffness, the location of the transfer story, structure of the chassis stiffness parameters influence on the structure. In the structure of long and short to respectively applied to acceleration response spectrum, draw the structure in seismic acceleration spectral response, drawing displacement curve and the angle of floor displacement curve, and the analysis of conversion board contained in seismic response and stress distribution. The results show that : the conversion of sheet thickness, stiffness, location, chassis stiffness paramete
