A post tensioned concrete T beam has a flange width of 525 mm and is 80 mm thick. The web is 125 mm wide and 550 mm deep below the flange. The prestressing cable 968 sq mm is 100 mm above bottom of web. Initial prestress is 1035 MPa. The beam is 9.15 m long on a simple span and is to carry a load of 11.67 KN/m. If prestressing losses amount to 15%, check the stresses at transfer and at working. Draw stress diagrams
