( Huayi Designing Consultants Ltd., Shenzhen 518031, China)Abstract: This engineering is a tall building overrun with high transfer floor, which has the height 99.9 meters, 2 floors underground, 32 floors above ground and the structural system is the frame-supported shear wall with girder transfer floor. Seismic design of this engineering is systematically introduced, including the structural system layout, elastic analysis of global structure, computation and adjustment of lateral stiffness, nonyielding design of important members under middle earthquake, elastic-plastic static pushover analysis and elastic verification of floor under rare earthquake, and local analysis of girder transfer floor. The implementation computation pointing to the character and difficulty of this engineering and the consequent structural adjustment and seismic strengthening measures are mainly introduced.
Keywords: tall building; high transfer floor; ratio of story drift; elastic performance of floor
