LATERAL
TIE CLIP DESIGN EXAMPLE
| Design Parameters: |
| (i) |
Seismic Design Requirement = 2.2 g = 2.2
(veneer dead weight) |
| (ii) |
Brick Veneer Dead Weight =
160 kg/m2 (32.8 lb/ft2) = 1.6 kN/m2 (0.232 psi) |
| (iii) |
Design Factor of Safety = 2.25 |
| (iv) |
Assume a Tie Spacing of 400 mm (16")
Horizontal x 600 mm (24")
Vertical |
| (v) |
Assume 4 Lateral Tie Clips per V-Tie™ (two on each leg) |
| Design Calculations: |
| Seismic Design Load |
= 2.2 (1.6 kN/m^2) = 3.5 kN/m2
[ = 2.2 (0.232 psi) = 0.5104 psi] |
Seismic Design Load
Per Tie |
= (3.5 kN/m2) (0.4 m) (0.6 m)
= 0.84 kN/Tie
[= (0.5104 psi) (16”) (24”)
= 196 lbs/Tie] |
Lateral Tie Clip Recommended
Design Load |
= 0.73 kN/Clip = 2.92 kN/Tie
[ = 164 lbs/Clip = 656 lbs/Tie] |
| Actual Factor of Safety |
= Lateral Tie Clip Ultimate Load
÷ Seismic Design Load
= (2.92 kN/Tie) ÷ (0.84 kN/Tie)
[ = (656 lbs/Tie) ÷ (196 lbs/Tie)]
= 3.5 (> 2.25) |
