Prestress losses:
a) Losses occur in pre-tensioned prestressed concrete members:
- Loss of prestress due to anchorage of slip.
- Loss of stress due to shrinkage of concrete.
- Loss of stress due to creep of concrete.
- Loss of stress due to elastic shortening of concrete.
- Loss of stress due to creep of steel or loss due to stress relaxation.
b) Losses occur in post-tensioned prestressed concrete members:
- Loss of prestress during the tensioning process due to friction
- Loss due to length effect.
- Loss due to curvature effect.
- Loss due to both length and curvature effect.
- Loss of prestress due to anchorage of slip.
- Loss of stress due to shrinkage of concrete.
- Loss of stress due to creep of concrete.
- Loss of stress due to elastic shortening of concrete.
- Loss of stress due to creep of steel or loss due to stress relaxation.
Loss of prestress during the tensioning process due to friction occurs in post-tensioned prestressed concrete members. Hence option (4) is the correct answer.
