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
