In order to study the wind loads on rectangular high-rise buildings, the wind pressures on seven rectangular high-rise buildings with various length-to-width ratios were tested in a wind tunnel where terrain category B was simulated. The sectional body shape coefficients with respect to wind azimuth and length-to-width ratio were calculated. The distribution of total body shape coefficients along with wind azimuth and length-to-width ratio was studied. Finally, the test results were compared with those obtained from the Load Code. The results show that, when body shape coefficients reach their maximum value, the azimuth is in the windward direction when the wind blows on the long side of the building. However, when wind blows on the short side of the building, the azimuth corresponding to the maximum body shape coefficients is at 20 degrees deviated from the windward direction. The body shape coefficients on the short side of the builing will decrease if the length-to-width ratio increases. The variation of body shape coefficients with depth-to-width ratio obtained from the tests is almost the same as that obtained from the Load Code. However, the variation exists between two sets of the coefficients. When the depth-to-width ratio is less than 1, some of the test data will be larger than the Code data and the maximum data occurs at the depth-to-width ratio of 1∶2. When the depth-to-width ratio is large than 1, the test data is smaller than the Code data.
