ABSTRACT:

The paper discusses the structural system selection and design for super tall building at intensive seismic zone. The heavy building weight and massive seismic load causes many difficult challenges for structural design of super tall buildings. In this paper, a sample tall building project is introduced and analyzed to discuss different aspects of consideration when deciding the most suitable structural system for such buildings. The sample tall building locates at Kunming city, one of most intensive seismic zone in China. The lateral force resisting system is a frame-core wall hybrid structure. The outer frame is composed of steel reinforced concrete (SRC) columns and steel ring beams. The core is strengthened by steel plate reinforced concrete (SPRC) section for critical locations. Outrigger cantilever truss and belt truss are also adopted and combined into MEP/Refuge floors for better seismic performance. Based on the sample project, following topics are discussed: major challenges for tall building design at intensive seismic zone; the structural option comparison and evaluation; balancing among structural safety, cost and architectural requirements.
