Abstract: To obtain thewind load andwind-induced responses of theChongqingMarriott International Conference Center Building, a tall steel structure building with a height of 303 m and the first frequency of0. 123 4 Hz, to evaluate its living comfortableness and safety, a wind-tunnelmodel test was carried outto simulate naturalwind in the turbulentboundary layeron the site of the building. The distribution ofwind pressure on every surface of the buildingwasmeasured by a staticmode,l and the static wind load was calculated. The wind-induced responses, including displacemen,t acceleration and angular velocity responses, were measured by an aeroelastic mode,l and the dynamic wind load was gained. The effects of its surrounding buildings and structureswere discussed. The result shows that the surrounding buildings have great effects on the wind load, no galloping will occur for the design velocity, the acceleration and angular velocity of the building top are smaller than their allowances and the living comfortability of the buildingmeets the related national code.
