Längsschweißnähte

Longitudinal welds of the reinforcing plates

l_{Schweißnaht} = \frac{P_{u}}{(2 Schweißnähte) \cdot ({ϕR}_{n})}

l_{Schweißnaht} = \frac{108.0 kips}{(2 Schweißnähte) \cdot (5.57 kips / in)}

l_{Schweißnaht} = 9.70 in \to 10.0 in verwenden

l_weld	Length of weld
P_u	Compressive load of (1) plate = F_y . A_g
F_y	Yield strength of plate = 36 ksi
A_g	Gross area of (1) plate = 0.375 in x 8.0 in = 3.0 in²
ΦR_n	Weld design strength per inch of weld
