UNIT REACTIONS FROM WIND GUIDE
DIRECTIVE: This guide is intended for use by a design professional. Design parameters shall
abide all specifications and limitations stated in this report. Design professional shall consider
all forces, including seismic and snow loads, per governing building code. Unit reactions
obtained from this guide shall be verified by a registered Professional Engineer. Reactions are
applicable for unit-to-host connections only. Sample calculations are provided below.
Design Parameters:
- Lateral Wind Pressure, P_lat- Uplift Wind Pressure, P_up
- Unit Height, H- Unit Depth, D
- Unit Width, W- Unit Weight, Wt
- Support Spacing across Depth, sd- Support Spacing across Width, sw
Unit Reaction Equations:
Long Side (Width x Height): Short Side (Depth x Height):
- Sliding Force, L = P_lat x W x H - Sliding Force, L = P_lat x D x H
- Uplift Force, U = P_up x W x D - Uplift Force, U = P_up x W x D
- Total Tension per Long Side = - Total Tension per Short Side =
( L x H/2 + U x sd/2 Wt x 0.6 x sd/2 ) / sd ( L x H/2 + U x sw/2 Wt x 0.6 x sw/2 ) / sw
Example:A (
stand, shall have the following unit reactions:
Long Side (Width x Height): Short Side (Depth x Height):
1.Sliding Force, L = P_lat x W x H 1. Sliding Force, L = P_lat x D x H
2 22 2
= (120 psf) x (48 in) x (42 in) x (1 in/ 144 ft) = 1680 lb = (120 psf) x (36 in) x (42 in) x (1 in/ 144 ft) = 1260 lb
2.Uplift Force, U = P_up x W x D 2. Uplift Force, U = P_up x W x D
2 22 2
= (95 psf) x (48 in) x (36 in) x (1 in/ 144 ft) = 1140 lb = (95 psf) x (48 in) x (36 in) x (1 in/ 144 ft) = 1140 lb
3.Total Tension per Long Side = 3. Total Tension per Short Side =
= ( L x H/2 + U x sd/2 Wt x 0.6 x sd/2 ) / sd = ( L x H/2 + U x sw/2 Wt x 0.6 x sw/2 ) / sw
= ( (1680 lb x 42/2 in) + (1140 lb x 24/2 in) = ( (1260 lb x 42/2 in) + (1140 lb x 48/2 in)
(250 lb x 0.6 x 24/2 in) ) / 24 in = 1965 lb (250 lb x 0.6 x 48/2 in) ) / 48 in = 1046 lb
