1. Determine the ultimate moment capacity of the T-beam shown below. The beam is reinforced with 6-632mm placed in two rows. Use fc=25MPa, fy=414MPa. 020 mm ???? 100 - d = 610 mm 8 - 32 mm 250 mm 2. Determinethe safe concentrated live load at midspan that the doubly-reinforced beam section shown can carry if it has a simple span of 5m. Use Pc=21MPa, fy=276MPa, unit wt of concrete = 23.54kN/m3. 360 mm 2- 25 mm Fd' = 80 d = 680 mm 780 mm B-6 36 mm 100 3. If in Prob. 2 the bottom bars are reduced to 6-832mm (3 in each row). Compute the safe concentrated live load at 1/3 span and 2/3 span the beam can carry.
