Experimental study on seismic performance of tall building with steel transfer trusses located at a higher level

Based on a shaking table experiment of 1 : 25 scale frame-shearwall structure model with steel transfer trusses, the dynamic characteristics, seismic responses in elastic and elastic-plastic phases with de- structive forms of the structure were studied. It was observed that cracks were developed with earthquake wave acceleration increasing, but no severe crack was developed in the structure during the experiment. In the seismic responses caused by artificial wave, site wave and E1 Centro wave, that caused by the artificial wave is the most intense one. Displacement angle between steel transfer trusses is large, which means the transfer stories might be weak. However, the seismic performance of the steel transfer trusses is good and the overall structure can satisfy seismic fortification requirements in the region of intensity 6.
