When viewing the wind maps, take the highest category number of the defined Risk or Occupancy category. Limiting values are free-standing canopy ( =0) and blocked canopy ( =1.0 ). roofs of structures not enclosed with permanent side walls). Table 5. On the other hand, pressure distribution for sidewalls (Zones A to C) are shown in Figure 7.5 of EN 1991-1-4 and depends on the\(e = b < 2h\). Table 9. need not be taken as less than one-third the length of the area. Hence, the effective wind area should be the maximum of: Effective wind area = 10ft*(2ft) or 10ft*(10/3 ft) = 20 sq.ft. In Section 26.2, there is a definition for effective area that indicates that the width need not be less than 1/3 of the span length. for a multibay duopitch canopy each load on a bay may be calculated by applying the reduction factors mc given in Table 7.8 to the values given in Table 7.7. Section 7.2.9 of EN 1991-1-4states that\({c}_{pi}\) can be taken as the more onerous of +0.2 and -0.3. Make sure that the selected file is appropriate for this calculation. For example, the values for blocked canopy may . if a roof is 6m wide and 4m tall then the edge area is defined as within 600m of the roof sides and of the roof top and bottom. NOTE: =0 represents an empty canopy, and =1 represents the canopy fully blocked with contents to the downwind eaves only (this is not a closed building). The characteristic value of sk snow load on a horizontal terrain is given in the national annexes to Eurocode 1 part 1-3. High excessive wind loads in a building could result in tension piles (expensive) in a piled foundation and require large cores/shear walls to distribute the load evenly through the building. To apply these pressures to the structure, we will consider a single frame on the structure. A helpful tool in determining the exposure category is to view your potential site through a satellite image (Google Maps for example). Figure 9. NOTE 2: The document 'BNCM/CNC2M N0380 / REC EC1-CM : July 2017 5.3' proposes a transformation of the force coefficients cf into a distribution of pressure coefficients along the slope of the roof, whose resultant is compliant, in size and position, to that defined by standard NF EN 1991-1-4 and the French National Annex.
