Determine the flexural strength of the beam. (ANS: Mn = 220.97kN.m) b) Determine the max. concentrated service live load that the beam could support. (ANS: PLL= 85.26kN) c) Determine the safe concentrated live load that could be carried by the beam using ASD. (ANS: PLL=80.68kN)
A beam is simply supported at the left end and is fixed at the right end. It is subjected
to a concentrated service dead load of 50 kN at its midspan. Assume the beam to be
laterally supported continuously throughout its length and has a compact section. Span
of beam is 6 m.
Prop. of beam
Zx = 990 x 103 mm3
Fy = 248 MPa
Sx = 316.5 x 103 mm3
U = 1.2 DL + 1.6 LL
Flexural resistance factor ø = 0.90
a) Determine the flexural strength of the beam. (ANS: Mn = 220.97kN.m)
b) Determine the max. concentrated service live load that the beam could support. (ANS: PLL= 85.26kN)
c) Determine the safe concentrated live load that could be carried by the beam using
ASD. (ANS: PLL=80.68kN)
