22 APPENDIX A. Worked Example: Wind action on a multi-storey building 1 of 18 Made by DC Date 02/2009 Calculation sheet Checked by AB Date 03/2009 1. Data This worked example deals with the determination of the wind action on a multi-storey building according to EN 1991-1-4. 10 m 120 m h h h p = 1,50 m 0 = 33,50 m = 35,00 m 1 1 Parapet Figure A.1 Dimensions of the building The building is erected on a suburban terrain where the average slope of the upwind terrain is low (3°). The terrain roughness is the same all around and there are no large and tall buildings in the neighbourhood. The fundamental value of the basic wind velocity is: V b,0 = 26 m/s The roof slope is such that:  < 5°
