For investigation of the wind load characteristics on high‐rise buildings with opening, a series of rigid rectangular high‐rise building models with opening were tested by synchronous multi‐pressure sensing system (SMPSS) in a boundary wind tunnel. Influence parameters including different opening heights, opening rates, opening patterns, and terrain categories are studied in detail. Based on the test results, the local wind force coefficients, base moment coefficients, and power spectral densities were discussed. The results indicated that the opening could affect the wind loads acting on high‐rise buildings to different extent. The distinct reduction of wind loads on high‐rise buildings was found at along‐wind direction, which could be evaluated by a proposed simplified expression accordingly. This study aims to provide useful information for the wind‐resistant design of high‐rise buildings with opening.

开敞式高层建筑风荷载特性试验研究

为了研究带开口的高层建筑的风荷载特性,在边界风洞中通过同步多压力传感系统(SMPSS)对一系列带开口的刚性矩形高层建筑模型进行了测试。详细研究了影响参数,包括不同的打开高度,打开速率,打开方式和地形类别。根据测试结果,讨论了局部风力系数,基本矩系数和功率谱密度。结果表明,开口可能不同程度地影响高层建筑的风荷载。沿着风向可以发现高层建筑风荷载的明显减少,可以通过提议的简化表达式进行评估。
