Abstract:This project is a super high-rise building. Based on the concept of design, according to the seismic principle andbuilding characteristics, the lateral stiffness efficiency and engineering economic index of several structural schemes werecompared and analyzed. Finally, the structural system of steel reinforced concrete frame-core tube without strengtheningstory was adopted. The performance design method was adopted in the seismic design, and a variety of software was used tocalculate the elasticity and elastic-plastic of the structure, and the seismic performance of the key and important componentswas checked according to the calculation results. The results show the indexes of the structure meet the requirements of thecode, and the structural design is reasonable. The whole system has good seismic performance and effective energydissipation mechanism.

Keywords:super high-rise building; frame-core tube structure; structure selection; performance-based seismic design;dynamic elastic-plastic time history analysis
