Extracted text: (18) Determine the plastic A W 18 x 40 beams are spaced at 2.4 m. on center. The beams are simply supported on a span length of 9 m. and support a 150 mm thick reinforced concrete slab. Assume A 36 #18-24 moment capacity of the beam. - (kN.m) (19) Determine the design flexural strength of the channel using LRFD – (kN.m) (20) Determine the allowable flexural strength of the channel using ASD – (kN.m) (21) Determine the value of P that can be applied to the beam due to its allowable N = 210 + Y steel and full lateral support of the compression flange. Unit weight of concrete is 24 kN/m3 Z = 1200 + Y Assume compact section h- 393,7 mm bending strength using ASD. - (kN) (22) Determine the safe service live load that can be applied to the beam due to its design bending strength using LRFD. - (kN/lm) (23) Determine the safe service live load can be Prop. of W 18 x 40 (wt. of beam = 60 kg/m) A = 7613 mm2 d = 454.66 mm applied to the beam due to its allowable bending strength using ASD. – (kN/m) (24) Determine the safe t = 13.34 mm br = 152.78 mm tw = 8 mm S, = 1121 x 103 mm3 service live load that the Z = Z x 103 mm Fy = N MPa U = 1.2 D + 1.6 L beam could support based on its shear capacity. ø = 0.90.
