抄録

Seismic performances of high-rise buildings are urgent to be studied given the background of the 2011 off the Pacific coast of Tohoku earthquake and probable long-period ground motions happened in subduction zone near east-coast of Japan. One 20 story frame of CFT and steel high-rise buildings were modeling, and seismic responses of models were simulated in FEM program with fiber model subjected to extreme ground motions recorded in the 2011 off the Pacific coast of Tohoku earthquake and the relevant artificial ground motions. Analysis results indicate that, the frame models could not satisfy the seismic demand under extreme ground motions. The CFT model has superior ultimate stability behavior than steel model as result of confinement effect of confined concrete to steel tubular. The phenomenon of deformation concentration along with vertical direction becomes more intense when the inputting acceleration level arrives extremely higher.
