Question
A T-beam w/ a flange width of 450 and a thickness of 175 mm has a total depth of 850mm. Thickness of web is 150 mm. The prestressed beam is provided by unbonded tendons with an effective prestress after all losses fse = 1100 MPa fpy 1. 1500 МPа f — 36 MPа. Compute the stress in the prestressed reinforcement at nominal strength if it has a span of 25 m. а. b. Determine the ultimate moment capacity of the beam if it is reinforced with unbonded tendons placed at 120 mm above the bottom of the beam. Aps = 1800mm² What is the ultimate uniform load that may be supported by the beam. (disregard the weight of the member) С.
