建立了一个数学模型，用于预测矩形几何形状建筑物上的三维风荷载，风垂直作用于建筑物表面。该方法允许评估频域中的力分布，包括平均风荷载和由顺风向和横风向大气湍流和尾流激励引起的波动荷载;不考虑自激力。所提出的技术的可靠性进行了验证，通过比较预测结果与文献中的实验数据。理论和实验结果之间令人满意的一致性证明了这种方法的良好适用性，但也强调了进行广泛的风洞和全尺寸实验的必要性，以提高对预测结果的正确性非常依赖的最相关的气动参数的认识。
A mathematical model to predict 3‐D wind loading on buildings with rectangular geometry and wind acting normally to a face is formulated. This methodology allows the evaluation of force distribution in the frequency domain including mean wind loads and fluctuating loads due to alongwind and acrosswind atmospheric turbulence and wake excitation; self‐excited forces are not taken into consideration. The reliability of the proposed technique is verified by comparing predicted results with experimental data available in the literature. The satisfactory agreement between theoretical and experimental results demonstrates the good applicability of this methodology, but also emphasizes the necessity of carrying out extensive wind tunnel and full‐scale experiments in order to improve the knowledge of the most relevant aerodynamic parameters on which the correctness of the predicted results strongly depends.
