2K6CE 705(A) PRESTRESSED CONCRETE

Module I (13 hours)
Basic concept of prestressing, advantages, materials and their characteristics – Systems and methods of prestressing, pretensioning systems, post tensioning systems, thermo elastic prestressing, chemical prestressing.
Module II (13 hours)
Loss of prestress – purpose of assessing losses, counteracting elastic loss, loss of prestress in case of nonuniform prestress, creep, shrinkage, relaxation and anchorage, friction Behaviour of prestressed concrete beams in flexure, load – deflection curves for prestressed concrete beams.
Module III (13 hours)
Elastic design of sections for flexure – design of a simply supported beam with symmetrical sections of post tensioned and pretensioned type – tension members.
Module IV (13 hours)
Bearing and anchorage zone – statically indeterminate structure – continuous beams – primary moment – resultant moment – concordant cable profile – Gyons theorem.
