Abstract: This paper simulates the average wind pressure distributions and space wind-induced responses of two super high-rise buildings in Haikou.Results show that irregular shape super high-rise buildings will have a larger displacement,and the construction of super high-rise buildings with irregular shapes should be avoided in northern area in Hainan,which provides an important basis for urban layout and new construction determined on the physical characteristics and height.Based on this,we summarize strategies and means for defending typhoon in urban planning in the northern area of Hainan,put forward some proposals on defending typhoon,expecting some prediction on the urban planning in tropical city full of typhoon in China.
