Abstract The effects of vertical splitter plates attached to the facades of high-rise building on the wind loads were investigated in details, based on a series of wind tunnel experiments. The rigid models with pressure taps were adopted, and totally one reference model and 16 models with different appurtenances configurations simulated by thin vertical splitter plates were studied. The testing results indicate that vertical plates can greatly affect the mean and fluctuating pressure on the building, the along-wind and across-wind layer forces and base moment. Continuous and stagger arranged vertical plates can significantly decrease the layer forces at the wind direction of 0° and the largest decrement of fluctuating across-wind layer force can reach 57.3%. It is also found that the back-to-back arrangement of vertical plates has the best effects on reducing fluctuating across-wind base moment with largest decrement of 51.3%. The reason of such results is further discussed in this study. According to the aerodynamic force spectra, the peaks of power spectra of models equipped with plates become lower than smooth surface model. The correlation coefficients of layer force along the building height and phase-plane trajectories of base moment are also examined.

竖板布置对高层建筑气动力特性的修正

摘要 通过一系列风洞试验，详细研究了附着在高层建筑立面上的垂直隔板对风荷载的影响。采用带测压孔的刚性模型，研究了1个参考模型和16个不同附件配置的模型，采用薄垂直分流板进行模拟。试验结果表明，竖板对建筑物的平均脉动压力、顺风和横风层力和基础力矩有很大影响。连续交错排列的垂直板可显着降低0°风向层受力，脉动横风层受力最大减量可达57.3%。还发现垂直板背靠背布置对降低脉动横风基力矩的效果最好，最大减量为51.3%。本研究进一步讨论了产生这种结果的原因。根据气动力谱，装有板的模型的功率谱峰值低于光滑表面模型。还检查了沿建筑物高度的层力的相关系数和基矩的相平面轨迹。
