A comparison and analysis on response between wind and earthquake action on tall buildings

A reinforced concrete frame structure in the area that seismic fortification intensity is six and basic wind pressure is 0.45kN·m-2 is selected in this paper,and wind and earthquake action are imposed to it respectively on ANSYS platform.Simulating wind uses the linear filtering method,and selecting EI-Centro wave to amplitude modulation can acquire earthquake wave.Base shear and moment,top floor displacement,story drift and top floor acceleration are selected to be compared and analyzed.Results show that the high-rise reinforced concrete frame structure according to wind resistance design can resist more severe earthquake in the region,but the possibility of that earthquake is dominant to the frame-shear wall structure and the shear wall structure is very large;To human comfort problem,it can be thought that frame structure should focus on the earthquake action according to the suitable height of each structure,but the shear wall structure and tube structure should focus on wind.
