Situation. A flooring system consists of parallel I-beam sections spaced at 3 m. on centers simply supported over a span of 9 m. The beam supports a 200 mm thick concrete slab of ultimate strength f'c = 21 MPa. The flooring system is designed for as ceiling and floor load of 750 N/m². The properties of the I-beam sections are: A = 11,500 mm² d = 350 mm; tw = 10 mm bf = 250 mm; t = 16 mm lx = 266x106 mm4 ly = 45 x 106 mm4 fy = 248 MPal Wb = 90 kg/m fy = 248MPa If each beam is laterally braced by the concrete slab, calculate the allowable bending strength using safety factor of 1.67.
