Question
A W410 x 46 beam section consisting of A 36 steel Fy = 248 MPa, Fu = 400 MPa has two
holes for 22mm diameter bolts in its tension flange. Fb = 0.66Fy. Assume diameter of hole is
3mm greater than bolt diameter.
Properties of W410 x 46
A = 5,890 mm2
d = 403 mm
bf = 140 mm
tf = 11.2 mm
tw = 7.0 mm
w = 46.2 kg/m
Sx = 773 x 103 mm3
Ix = 156 x 106 mm4
a. Determine the effective tension flange area.
b. Determine the amount of moment of inertia to be reduced due to the effect of holes.
c. Determine the safe concentrated load that it could support at the midspan besides its own
weight if it has a simple span of 8m.
