Design Problem 3 The pretensioned circular beam shown below has straight cables with initial stress of 1500 MPa and final stressess after losses of 100 MPa. The beam span length is 7.50 m. Determine the deflection at the beam centering (use initial). Ec = 27,000 MPa. Assume the concrete is uncracked. The prestress steel is Aps = 874.195 mm². Unit weight of concrete is 24 kN/m³. Concrete cover is 100 mm DL Beam weight only LL = 12 kN/m D=700 mm
