Abstract:Application difficulties of seismic isolation technology in the project were introduced systematically, including : isolation design method, finite element analysis method and support and damper unit mechanical model, isolation layer eccentricity checking method. A concrete and feasible solution was proposed for the wind resistance requirements of the high-rise building structure isolation design with a large windward side. Dynamic elastic-plastic analysis was carried out by software of ABAQUS 6.11. The requirements of support tension and structural anti-overturning in the high-rise isolation were validated and analyzed. The results show that after solving the above technical problems, it is feasible to adopt the isolation technology in the high-rise shear wall structure in the high-intensity area. It is helpful to the application of the isolation technology in the high-rise residential building.
Keywords:fracture zone; seismic isolation design; wind requirement; dynamic elastic-plastic analysis
