Steel Buildings in Europe

Title APPENDIX B. Worked Example: Wind action on a single-storey building 9 of 11 3 - 54 5. Wind forces on surfaces F / A ref = c s c d q p ( z e ) c pe – q p ( z i ) c pi with: c s c d = 1 (height < 15 m) q p ( z e ) = q p ( z i ) = 0,66 kN/m 2 The figures below show the wind forces per unit surfaces: F / A ref = 0,66 ( c pe – c pi ) (in kN/m 2 ) EN 1991-1-4 § 6.2(1)b Wind +0,33 -0,99 -0,53 -0,46 -0,33 -0,92 -0,66 -0,46 F fr = 8,32 kN Figure B.6 Wind on gable with c pi = +0,2 Wind +0,66 -0,66 -0,20 -0,13 0 -0,59 -0,33 -0,13 F fr = 8,32 kN Figure B.7 Wind on gable with c pi = -0,3
