5 A T-shaped simply supported beam has the cross section shown in Figure P1.4. It has (11 m), is loaded with a gravity live-load unit intensity W = 2,500 plf (36.5 kN/), and with twelve -in.-dia (twelve 12.7-mm-dia) seven-wire stress-relieved strands. Com crete fiber stresses at service load by each of the following methods: (a) Basic concept (b) C-line (c) Load balancing Assume that the tendon eccentricity at midspan is e,= 9.6 in. (244 mm). Then given th fi - 5,000 psi (34.5 MPa) f. - 12Vf: - 849 psi (5.9 MPa) - 165.000 psi (1,138 MPa)
