A 13-storey tube-in-tube structural model with transfer storey was made with scale of 1∶ 10. The bottom five lays of the model are concrete filled steel tubular frame-supporting columns,and on-ground reinforced concrete corewall is adopted inside. Structural form of the model is complicated because there is high-level transfer and vertical stiffness mutation. In order to master the seismic performance of this complex high-rise building structure,horizontal loadings under different working conditions were exerted on the model to test the static...
