Orientation of Industrial sheds and Strong Wind effects

It is possible to use directional distribution data of winds together with pressure coefficients obtained on the model of an industrial structure in wind tunnel testing to obtain optimum layout of industrial complexes. It is assumed that the industrial structures in a particular complex will not vary widely with the values of height to width ratio, length to width ratio and the roof slopes remaining nearly the same. Wind velocity varies in a random manner in both time and space. Hence even on a rigid structure the load effects vary with time. This leads to enormous number of load cycles of differing magnitude during the life of a structure, leading to accumulation of fatigue damage. When such structures are located in cyclone prone regions, one of the basic considerations for planning could be minimisation of fatigue damage prior to exposure to an extreme wind event like cyclone
