Study On The Influence Of High Aspect Ratio On Seismic Response Of Tall Building Structures

The high-rise building in order to meet the requirements of ventilation and lighting,generally reduces the width of the structure,in addition to the height of the structure is also more and more high,which resulted in the structure of high aspect ratio than the standard,may lead to the failure of foundation under strong earthquake,but in the structure design for the basic design or separate design,not considered the interaction of superstructure and foundation to the overall design of the building structure?In this paper,the main work of this paper is based on the analysis of the interaction between superstructure and foundation under seismic action:(1)the development of high-rise buildings and the development of the joint function are introduced in detail?(2)this paper introduces the advantages and disadvantages and the applicable conditions of each model of the interaction between superstructureand foundation?(3)this paper is based on the simulation of ETABS soft software,and introduces the application condition and the cell library of the software?(4)according to the practical engineering in considering the interaction and not considering the interaction model was established,in the rare case input ground motion under three seismic waves,comparing the two models in the three wave of the maximum value,to consider the interaction with and without consideration of the interaction of vibration period,deformation and the change of internal forces,design for future reference to?(5)to change by changing the structure of the high aspect ratio,high aspect ratio comparison of different internal structure considering interaction in the rare event of superstructure under earthquake and the pile body and the deformation in the high aspect ratio structure changes,for the practical use of high aspect construction internal force and displacement in the design of the building and provide reference ratio?...
