7 The beam with a cross-sectional area of 350 mm x 600mm isprestressed by using a bonded (stress relieved tendons) with an fpu =1350MPa. If fc’=30MPa., determine the safe ultimate moment capacity of the beam.Aps=1230𝑚𝑚2 , fpy=1160MPa
14 Compute the safe ultimate moment of a T-beam beam with aflange width 2500mm, flange thickness of 80mm, web thickness of 300mm and anoverall depth of 900mm. The beam is reinforced with an unbonded tendon having anarea Aps = 1000mm2 and located 80mm from the bottom fiber of the beam, fc’=35MPa. The beam has a simple span of 6m.
