11.) A simply supported 11-m span beam, 300-mm wide by 530-mm deep, is pre-stressed by straight tendons with Aps = 774 mm2 located 70 mm from the bottom at an iniitla prestress of 1.10 GPa. Calculate the concrete stress in MPa at the bottom fiber of the beam at midspan immediately after 12% losses in the tendons are in effect. 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.
