Abstract
Eight L-shaped rigid models with different geometric dimensions were tested at four typical terrain categories in a boundary wind tunnel to investigate the characteristics of wind pressures on L-shaped tall buildings. The effects including wind direction, turbulence intensity, and geometric dimension on the characteristics of wind pressures on L-shaped tall buildings were studied. Shape factors of each face under the unfavorable wind direction were summarized. Moreover, the power spectral densities, correlation coefficients, and coherence functions were analyzed in frequency domain. Based on the testing results, it is shown that the proposed exponential functions fit the measurements well. The objective of this study is to provide useful information for the wind-resistant design ofL-shaped tall buildings.
