Abstract: T1 of China Resources Center in Kunming is a super high-rise building with 8-degree seismic fortification. Thetotal height of the building is 297m. It is a mixed structural system of concrete-filled steel tube frame-section steel ( steelplate) concrete core tube with reinforced layer. The finite element software was used to study the changes of the wholestructure under earthquake action after reducing the structural dead weight, reasonably controlling the tensile stress of shearwall, setting the stiffening layer with finite stiffness and setting the buckling restrained braces, etc. At the same time, thestress characteristics of components under earthquake action were studied. The results show that the lateral stiffness of thewhole structure is increased and the material consumption is reduced. All indexes satisfy the requirements of standard andachieve the objective of expected seismic performance.

Keywords:China Resources Center in Kunming; super high-rise structure; steel plate concrete shear wall; seismic-energydissipation; buckling restrained brace; outrigger reinforcement layer; pin joint
