PROBLEM 3
A W 14 x 68 having the following properties:
Prop. of W 14 x 68
d = 356.62 mm
bf = 254.89 mm
Sx = 1688 x 103 mm3
Zx = 1885 x 103 mm3
E = 200000 MPa
Elastic buckling stress: Fcr = 420 MPa
Cb = 1.14
Lp = 2.65 m
Lr= 8.05 m
tf = 18.29 mm
Fy = 345 MPa
Determine the flexural strength of the beam if the beam has a
a)
continuous lateral support.
b) Determine the flexural strength of the beam if the beam has an
unbraced length of 6 m.
Determine the flexural strength of the beam if the beam has an
c)
unbraced length of 12 m.
