Shape: Wide-flange
Imperial designation: W44x230

Properties:

D = 1090mm
B = 400mm
t = 31mm
w = 18mm
Fy = 350MPa
E = 200000MPa

Bearing Resistance

Interior load

&Phibi = 0.80
Bearing resistance of the web shall be the smaller of:
(i) Br = &Phibi*w*(N+10*t)*Fy = 2066.4kN
(ii) Br = 1.45*&Phibi*w2*(Fy*E)0.5 = 3144.5kN

Br = 2066.4kN

P/Br = 0.048 OK - No stiffener required
