![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 ultima
strength fc = 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 = 266x105 mm4
ly = 45 x 105 mm4
fy = 248 MPa
Wb = 90 kg/m
fy = 248MPa
Calculate the service floor live load (kPa) each beam can sustain in bending under allowable stress design method.
