A T-beam for a floor system has a slab thickness of 75 mm and a web thickness of 375 mm. It has an effective depth of 600 mm. The beam carries a dead load moment of 280 kN-m and a live load moment of 525 kN-m. It has a span of 5.4 m and a spacing center to center of 1.8 m. Use reduction factor ø=0.90, fc’=20.7 MPa, fy = 344.7 MPa. Determine the effective width of flange.  Determine depth of compression flange.  Determine the required steel area.  See the formula in the image
