Abstract: Chongbin-Baoli Plaza is 286.8m high, which located at Chongqing Yuzhong district. The RC frame-core wall structural system is used for the tower. The structural form selection, design characteristics of foundation, basement and upper structures were introduced. Bearing capacity of the concrete filled steel tube designed according to different codes was compared, and the wind load shape coefficient was determined by results of wind tunnel test. Finally, the rigidity-gravity ratio and gravity second-order effect were researched and discussed.

Keywords: super high-rise building; strengthened story; concrete filled steel tube; rigidity gravity ratio; gravity second-order effect
