A concrete beam is pre-stressed by a cable carrying an initial pre-stressing force of 300 kN, the area is 300 mm2. What is the percentage of loss of stress due to shrinkage in pre-tensioned members?
A post-tensioned concrete beam is prestressed by means of three cables each 100 mm2 area and stressed to 1100 MPa. All three cables are straight and located at an eccentricity of 50 mm. If modulus modular ratio (m) = 6 and stress in concrete at the level of steel (Fc) = 5 MPa, then what is the loss of stress in cables due to elastic shortening if all cables are simultaneously tensioned and anchoring?
A simply supported rectangular prestressed concrete beam is subjected to uniformly distributed live load over its entire span, such that the resulting stress at the midspan at bottom fibre is zero. The eccentricity at that section is d/6 below the C.G., where d is the depth of the beam. Location of the thrust line at that section is
