The 300 meters long sky corridor bridges the four 230 meters high towers at the top floor. The complexity of the structure makes it very difficult for seismic resistance design. To reduce earthquake response and member forces of the towers and skycorridor, passive control strategy is adopted. Connection joints between the towers and sky corridor are designed as flexible links. Friction pendulum bearings and viscous dampers are installed in the connection joints. To Study the seismic performance of this complex structure, a 1/25 scaled model structure was tested on the shaking table under minor, moderate, and major earthquake levels. Eight earthquake records with different frequency spectrum property were selected to test the model structure. The maximum responses of acceleration and deformation of the four towers and sky-corridor were measured, and the seismic performance of friction pendulums ,viscous dampers, dynamic characteristics, cracking pattern, failure mechanism of the building were also evaluated. Results show that using friction pendulum bearings and viscous dampers to connect the sky corridor to the four towers can effectively reduce earthquake responses of each tower and member forces of the sky corridor if the properties of friction pendulum bearings and viscous damper are appropriately selected.
