PROBLEM 4 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 = 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 strenath of the beam
