Tianhong Plaza is a complex high-rise building with 3 floors underground, 5~7 overground floors, building height of 28~39m, and steel reinforced concrete frame structure. Such problems as torsional irregularity, concave convex irregularity, partial floor slab discontinuity and super-long structure are encountered simultaneously during the design of upper structure, which is a major problem for seismic overrun and super-long structure design. In this paper, the abovementioned problems have been effectively solved by adopting structure seismic-resistant performance design to enhance the weak pocket of structure and check on temperature, and take corresponding structure measures.
