In this study, the aerodynamic characteristics of tall buildings with corner modifications (e.g., local wind force coefficients, mean pressure distributions, normalized power spectrum density, and extreme local pressure) were examined. Wind tunnel experiments were conducted to measure the wind pressures on building models with different heights and recessed corners of different ratios. At a wind direction of a = 0° (i.e., wind blowing on the front of a building), corner modifications effectively reduced wind forces in all cases. Specifically, small corner modification ratios reduced wind forces more effectively than their larger counterparts. However, corner modifications resulted in extreme local pressure on building surfaces. In addition, for small corner modification ratios, the probability of extreme local pressure occurring at a = 0° was high. This probability was also high for large corner modification ratios at a = 15° (i.e., wind blowing slightly obliquely on the front of a building) because wind blowing obliquely creates substantial vortex shedding on one side surface and extreme negative pressure over one building side surface. Results of computational fluid dynamic modeling were adopted to determine details of the aerodynamic characteristics of tall buildings with corner modifications.

在这项研究中，检查了带有角部修改的高层建筑的空气动力学特性（例如，局部风力系数，平均压力分布，归一化功率谱密度和极端局部压力）。进行风洞实验以测量具有不同高度和不同比率的凹角的建筑模型上的风压。在风向a= 0°（即，风吹在建筑物的正面），在所有情况下，边角修改均有效地减小了风力。具体而言，较小的转角修改比比较大的修改更有效地减少了风力。但是，拐角处的修改会导致建筑表面承受极大的局部压力。此外，对于较小的拐角修改率，在a = 0°处出现极端局部压力的可能性很高。这个概率也高在大型的角落修改比一= 15°（即，风向建筑物前部稍微倾斜），因为风向倾斜会在一侧表面上产生大量涡旋脱落，并在一侧建筑物表面上产生极大的负压。通过计算流体动力学建模的结果来确定带有角部修改的高层建筑的空气动力学特征的细节。
