A prestressed beam is given in the figure below. X Aps = 696 mm2 H = 540 mm B = 350 mm y = 90 mm L = 9.7 m If the initial prestress is fps,i = 1,208 MPa, calculate the stress at the top fiber, at midspan section due to prestress and self-weight. Input the answer in MPa, wtih decimal places including the sign. + for tension, - for compression. Aps mm B (mm)→ II (mm) y (mm) L (m)
