Structural system selection and analysis of main tower building of Founder Financial Center

The main tower building of Founder Financial Center has a structural height of 230.80 m, and adopts a frame-corewall structural system with strengthened stories. The outer frame is composed of concrete-filled steel circular tubular columns and solid web steel beams, and the corewall adopts steel plate composite shear walls, and two strengthened stories are set at the building refuge story and the equipment story to improve the rigidity of the overall structure. The structural system selection and characteristics of the structure of the project were introduced emphatically, as well as the connection structures and characteristics of steel plate composite shear walls, the optimal setting of outriggers and belt trusses and the overall calculation results. The results show that the main indicators of the overall structure meet the requirements of the code, and the structural system is reasonable.
