Question 39
CEMCQ2 marksNeeds review
A post-tensioned concrete member of span 15 m and cross-section of 450 mm × 450 mm is prestressed with three steel tendons, each of cross-sectional area 200 mm². The tendons are tensioned one after another to a stress of 1500 MPa. All the tendons are straight and located at 125 mm from the bottom of the member. Assume the prestress to be the same in tendons and the modular ratio to 6. The average loss of prestress, due to elastic deformation of concrete, considering all three tendons is
