Structures must be able to withstand the external loads imposed by nature. Wind is one of the major forces responsible for the catastrophic failure of structures and loss of life. Therefore, accurate evaluation and prediction of wind loads and proper mitigations are very important in reducing the adverse effects of wind in the built environment. In addition to the mean and the background (due to turbulent fluctuations) loads on rigid buildings, flexible structures will be subjected to resonant wind loads as well. The primary source of the wind motion is the pressure fluctuations in the windward and leeward faces due to the fluctuation in the approach flow and its interaction with the building. Building codes and Standards usually provide loads along the wind direction for common shapes in open and suburban terrain category. Wind pressure on a structure is a function

结构必须能够承受自然界施加的外部荷载。风是造成建筑物灾难性破坏和生命损失的主要力量之一。因此，准确评估和预测风荷载并采取适当的缓解措施对于减少风对建筑环境的不利影响非常重要。除了刚性建筑物上的平均和背景（由于湍流波动）荷载外，柔性结构也将受到共振风荷载。风运动的主要来源是由于进场气流的波动及其与建筑物的相互作用而引起的迎风面和背风面的压力波动。建筑规范和标准通常为开阔和郊区地形类别中的常见形状提供沿着风向的荷载。结构上的风压是一个函数
