Abstract: The height of an intended residential building in Haikou is up to 137m, which exceeds the maximum allowable height of grade B buildings in design code. In addition, the project locates in 8.5 degree seismic intensity area and the site category is group Ⅲ, which brings adverse effects on anti-seismic of the structure. Based on SAUSAGE program, explicit dynamic method was adopted and geometric and material nonlinearity were included in elastic-plastic time-history analysis in rare earthquake. Degree of damages in shear wall and coupling beams is mainly researched and studied to check the seismic performance of the building. The result shows that no obvious damage appears in shear wall, and full developments of plasticity in coupling beams, which suggest good seismic performance of the structure.
Keywords: ultra high-rise residential building; elastic-plastic time-history; damage factor; seismic performance
