英文摘要	The Lanzhou Red Mansion Times Square is a complex super high-rise building, which exceeds the code limitations in terms of torsional irregularity and structural height. It uses the frame-core wall system and strengthened stories with outrigger trusses as lateral force resisting system. Shaking table test of 1:25 scaled model was conducted to study its acceleration response, displacement response and dynamic strain response of key parts under various seismic actions from frequent to rare earthquake levels. The weak zones were identified and seismic behaviors were evaluated. Some design suggestions were proposed, including the appropriate adjustment of lateral stiffness of weak story and the adjacent story, steel reinforcement of high coupling beams of the core tube, and so on. Research results show that: although the strengthened story with outrigger trusses changes abruptly local rigidity and bearing capacity and results in weak zones, by adjusting the outrigger truss or the adjacent story column stiffness, the adverse effects of the strengthened story with outrigger trusses can be reduced comparatively. Model structure does not collapse under 8 degrees rare earthquake, showing the structure has a good seismic performance and can be applied to high seismic intensity area.
