Abstract：Wind pressure measurements of tall buildings with openings were carried out in a Boundary Layer Wind Tunnel. Based on the test results, the influence of the openings on the wind loads on the tall buildings was investigated. The results indicate that the openings can reduce the base wind loads on the buildings. The reduction of along-wind mean base shear for the case when the openings are on upper parts is very close to that when the openings are located on the lower parts. But the former case is more favorable for decreasing the along-wind mean base moment and the across-wind RMS base moment. Empirical formulas for calculating the relative value of the along-wind mean base moment coefficient and the across-wind RMS base moment coefficient are proposed. The distributions of wind force at each floor on the tall buildings with openings are quite different to those without opening, which deserves special attention in wind-resist design of tall buildings with openings.
