Design a simply supported prestressed beam of 8.5 m span carrying a superimposed dead load of 5 kN/m
Design a simply supported prestressed beam of 8.5 m span carrying a superimposed dead load of 5 kN/m and service live load of 7 kN/m. Normal weight concrete of fo = 40 MPa and fái = 30 MPa and seven wire steel strands of Grade 1725 are to be used with fpy = 1550 MPa. The section is to be of symmetrical I-shape and the eccentricity of prestress force will be varied along the span according to the bending moment diagram. The losses after transfer are estimated to be 15%. The member is required to be of class-U May 05 2022 06:28 PM
