Due to the strike of wind-blown raindrops, the pressure caused by wind and rain on building facades is different from the action of wind-only. The wind–rain induced pressure during Typhoon Haikui (2012) was collected at three taps on the windward side of Tongji University experimental building which was located near the coast of East China Sea. The observed data during the storm was compared with both the data of normal wind events without rains and wind tunnel test. The results show that the presence of driving rains intensifies the wind effects acting on the windward side of the building. More specifically, the mean wind–rain induced pressure coefficients at the three locations of the experimental building are larger than those collected from the strong wind-only events and the wind tunnel test when the wind direction ranges from 110° to 130°. It was also found that the mean wind–rain induced pressure coefficients at each tap increase in magnitude with rainfall intensity and the distance between the pressure tap and the wall corner. Similarly, the fluctuating wind–rain induced pressure coefficients are larger in comparison to the wind-only pressure coefficients from the full-scale measurement and wind tunnel test. However, the coefficients decrease with the distance from the wall corner in the case of 80°–140° wind directions. In addition, it was found that Gamma distribution is a robust model to represent the probability distribution of the wind–rain induced pressure coefficients. High quality of pressure correlation was observed among three taps, regardless of the rainfall intensity. By contrast, the presence of driving rains slightly reduces the correlation of wind–rain induced pressure.

台风海葵期间低层建筑风雨诱导压力的现场调查

由于风吹雨滴的撞击，风和雨对建筑立面造成的压力与仅风的作用不同。台风海葵（2012）期间的风雨诱导压力在位于东海沿岸的同济大学实验楼迎风侧的三个水龙头处收集。将风暴期间的观测数据与没有降雨的正常风事件和风洞试验的数据进行了比较。结果表明，暴雨的存在加强了作用在建筑物迎风面的风效应。更具体地说，当风向范围为110°至130°时，实验建筑物三个位置的平均风雨诱导压力系数大于仅强风事件和风洞试验收集的数据。还发现每个水龙头的平均风雨诱导压力系数随着降雨强度和压力水龙头与墙角之间的距离而增加。类似地，与来自全尺寸测量和风洞试验的仅风压力系数相比，波动的风-雨诱发压力系数更大。然而，在80°～140°风向的情况下，系数随着距墙角的距离而减小。此外，还发现 Gamma 分布是表示风雨诱导压力系数概率分布的稳健模型。无论降雨强度如何，在三个水龙头之间都观察到了高质量的压力相关性。相比之下，
