3 - 46 APPENDIX B. Worked Example: Wind action on a single-storey building 1 of 11 Made by DC Date 06/2009 Calculation sheet Checked by AB Date 07/2009 1. Data This worked example deals with the calculation of the wind action on a single-storey building according to EN 1991-1-4. The overall dimensions of the building are given in Figure B.1. 14 ° 5 m 5 m 6 m 6 m 4,8 m 6 m 16 m 16 m 60 m Figure B.1 Geometry of the building The doors are assumed to be shut during severe gales. The fundamental value of the basic wind velocity is: v b,0 = 26 m/s 2. Peak velocity pressure The peak velocity pressure is determined according to the step-by-step procedure given in this guide. 1. Fundamental value of the basic wind velocity v b,0 = 26 m/s 2. Basic wind velocity For c dir and c season , the recommended values are: c dir = 1,0 c season = 1,0 Then: v b = v b,0 = 26 m/s EN 1991-1-4 § 4.2(2)
