Influence Of The Connection Position And Rigidity Variation On Seismic Response Of The Connected Tall Building Of Twin Tower

The connected tall building of twin tower can make full use of the land and ithas unique architectural effect. The existence of corridor make the separatedbuildings become one. The dynamic characteristics and earthquake resistantbehavior change a lot than before.The article first will introduce the classification、feature、Research Status ofconnected building; expound on the development of and fundamental about finiteelement; sketch the main step of model analysis and the method of dynamictime-history seismic analysis we needed in this article.The following article will set up a special model of symmetrical structure;then change the corridor position and rigidity and do the dynamic time-historyseismic analysis for the frame by means of universal finite element analysissoftware Sap2000. Discuss the influence of natural vibration period, displacementof top story, relative story displacement and base shear from different corridorabout position and rigidity. Compare the Analysis Results and then find out the bestposition and rigidity of the corridor. At last, get a single tower from the doubletower to analysis. Obtain the seismic response from the different earthquake waveand analysis the influence of the corridor existence though comparing with doubletower.
