- 2nd: A simply supported 14-m span beam, 300-mm wide by 540-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. Calculate the concrete stress in MPa at the bottom fiber of the beam at midspan immediately after the tendons are cut. Write your answer in 2 decimal places only. Use unit weight of concrete 24 kN/cu.m. Sign convention is (+) tension, (-) compression. Indicate the sign in your final answer.A rectangular reinforced concrete beam has a width of 300 mm andan effective depth of 450 mm to centroid of the tension bars.
