英文摘要	Conference Name:4th International Conference on Civil Engineering, Architecture and Building Materials, CEABM 2014. Conference Address: Haikou, China. Time:May 24, 2014 - May 25, 2014.; In this paper, 2 high-rise building models with ladder and cascade irregularities of elevation were tested in a wind tunnel respectively to measure the mean and fluctuating wind pressure distributions. The mean and RMS (root-mean-square) coefficients of the drag, lift and torsion moment on the measuring layer were obtained from the wind pressures. In the direction which the buildings were positive in the wind, the variation of these above mentioned coefficients with height and the power spectrum densities of the fluctuating wind loads on sudden changed positions were analyzed in detail. Compared with the elevation regular tall building, the wind load characteristics of irregular ones were more complicated. ? (2014) Trans Tech Publications, Switzerland.
