Research on Dynamic Response with Complicated Structure System

With the complex high-rise and extra-high buildings construction, dynamic characteristics of these structures are more and more paying close attention and researching. At the same time, the dynamic response of high-rise building with complicated structure system is always a hot and difficult research, and it is going to be further developed on the research of dynamic features, displacement and internal force. Selecting a complicated systematical structure of a city, using finite element to establish the model and inputting rare earthquake wave, this paper carried out an analysis on the natural vibration characteristics, relative storey displacement and maximum shear of the structure by applying dynamic elastoplastic time history analysis method, drawing the conclusion that the structure design is safe and putting forward the corresponding improvement measures.
