For distribution of windward pressure (Zone D), Section 7.2.2 of EN 1991-1-4 describes the how it should be distributed depending on \(h\), \(b\), and \(d\). The first thing to do in determining the design wind pressures is to classify the risk category of the structure which is based on the use or occupancy of the structure. Table 1. Take note that a positive sign means that the pressure is acting towards the surface while a negative sign is away from the surface. Why are the tolerance zones between the zone borders 5km wide on the online snow load map of Austria? Supporting structures for canopy roofs cannot be calculated automatically. To apply these pressures to the structure, we will consider a single frame on the structure. http://goo.gl/MRGajL for more FREE video tutorials covering Structural Design & LoadingThis video elaborates the calculation of wind pressure acting on roof . Table 11. Internal Pressure Coefficient, \(({GC}_{pi})\), From these values, we can obtain the external pressure coefficients, \({C}_{p}\).
