A T-beam section has a flange width of 600 mm, flange thickness of 100 mm, width of web of 350 mm, effective depth of 535 mm and a total depth of 600 mm. Use f'c = 21 MPa and fy = 415 MPa. The section is required to resist a total service dead load moment of 260 kN-m and a service live load moment of 142 kN-m. Use o = 0.90 and U = 1.2D + 1.6L. 1. Determine the required nominal strength for the concrete beam section. 2. Determine the maximum height of the rectangular stress block for a tension- controlled section. 3. Calculate the required depth of the concrete rectangular stress block.
