Development of a simplified procedure to predict wind loading on structures using the Computational Fluid Dynamic (CFD)

结构必须能够承受自然施加的外部荷载。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，对风荷载进行准确的评估和预测，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荷载和背景荷载(由于湍流波动)外，柔性结构还将受到共振风荷载的作用。风运动的主要来源是迎风面和背风面的压力波动，这是由于进场气流的波动及其与建筑物的相互作用。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风向的荷载。结构上的风压是一个函数

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
