6. A concrete floor system consists of parallel T beams spaced at 3 m on centers and spanning 9.6 m between simple supports. The 150 mm thick slab is cast monolithically with T beam webs having width 350 mm and total depth, measured from the top of the slab, of 700 mm. The effective depth will be taken 75 mm less than the total depth. Each T-beam must carry a superimposed dead load of 2.4 kPa and service live load of 10.77 kPa with material properties Yc = 24 kN/m3, f' = 21 MPa and fy = 275 MPa. 6.1. Determine the maximum factored midspan moment in kN-m. 6.2. Determine the effective flange width of each I beam required by NSCP in mm. 6.3. Determine the required amount of steel reinforcement at mid-span of an interior beam. Assume 20 mm bar diameter for flexure and 10 mm for stirrups.
