Wind Force on Solid Freestanding Wall / Sign
Design wind force and Case B eccentric (torsion) moment on a solid freestanding wall, monument sign, or pylon: ASCE 7-22 Section 29.3, F = qh G Cf As with a net two-face Cf from Fig 29.3-1 (~1.2-2.0, not a building-wall +/- GCp). The 0.2B eccentricity, not the straight force, sizes the post and footing.
Formula and source
F = qh G Cf As; Case B eccentric moment M = F x 0.2 x B.
The ASCE 7-22 Section 29.3 design wind force on solid freestanding walls and signs, F = qh G Cf As, with Cf from Figure 29.3-1, by name.
