This is already answered in Bartleby but I think the answer is incorrect. Please check and answer correctly. RATE WILL GIVEN! A simply supported 12-m span beam, 300-mm wide by 550-mm deep, is pre- stressed by straight tendons with Aps = 774 mm² located 70 mm from the bottom at an initial prestress of 1.10 GPa. What maximum service uniform live load can the beam support in addition to its own weight if allowable tensile stress in concrete 0.5 x square root of f'c is permitted. after 17% loss Write your answer in 2 decimal places only. Use fc = 30 MPa unit weight of concrete 24 kN/cu.m. Sign convention is (+) tension, (-) compression. Indicate the sign in your final answer.
