Abstract


Because of the mutation of vertical stiffness,twin-tower high-rise building structure,commonly used by high-rise building structure,is complexity of dynamic behavior with poor seismic behavior.The suited dynamic analysis model of high-rise building structure was picked and chosen.In this paper,the twin-tower high-rise building was at Xian as an example.The finite element program SAP2000 was used in dynamic analysis.And the models of the single-tower high-rise building with enlarged base and the twin-tower high-rise building with enlarged base were built.Modal analysis and response spectrum analysis and elastic time-history analysis,in a one-way seismic,were done.Through the analysis,it compared to the difference of dynamic behavior between the single-tower high-rise building with enlarged base and it sorted out the laws of dynamic changes.Lastly,it summed up the seismic behavior of twin-tower high-rise building with enlarged base in this paper.The suggestions of design for improving the seismic behavior of twin-tower high-rise buildings with enlarged base were put forward,and some unsolved problems were put forward too.
