A flooring system consists of parallel I-beam sections spaced at 3 m on centers with simple spans of 6m. The beam supports a 200mm thick slab that laterally supports the top of the beams. The flooring system is designed for a superimposed load of 1750 N/m^2 The properties of the I-beam sections are: d= 352mm, tw= 7mm bf=170 mm, tf= 10mm Ix= 0.00012m^4, W= 44.85 kg/m Fy- 248 MPa,E= 200,000 GPa 1. Calculate the plastic section of the steel section in mm^3 2. Calculate the nominal strength (kN.m) of an individual beam if it is laterally supported by the concrete slab. 3. Calculate the unfactored service dead load on an individual beam in kN/m

1. Calculate the plastic section of the steel section in mm^3
2. Calculate the nominal strength (kN.m) of an individual beam if it is laterally supported by the concrete slab.
3. Calculate the unfactored service dead load on an individual beam in kN/m
4. Calculate the maximum service live load (kPa) the beam can sustain under LRFD provisions using φb= 0.9
5. Calculate the maximum live load (kPa) the beam can sustain under ASD provisions using Ωb=1.67
