Title APPENDIX B. Worked Example: Wind action on a single-storey building 4 of 11 3 - 49 + 0,7 - 0,3 Wind 44 m h = 8 m 3,2 m 12,8 m - 0,5 - 0,8 - 1,2 D B C E A Figure B.2 c pe,10 for zones A, B, C, D and E with wind on gable 2. Wind on the long side h = 8 m b = 60 m (crosswind dimension) h < b , so z e = reference height = h = 8 m d = 32 m EN 1991-1-4 7.2.2 (1) Figure 7.4 h / d = 8/32 = 0,25 2 h = 16 m EN 1991-1-4 § 7.2.2(2) Table 7.1 e = 16 m ( b or 2 h , whichever is smaller) e < d e /5 = 3,2 m 4/5 e = 12,8 m d – e = 16 m EN 1991-1-4 § 7.2.2(1) Figure 7.5 Figure B.3 defines the external pressure coefficients c pe,10 on vertical walls for zones A, B, C, D and E with wind on the long side.
