In pretensioned concrete members, strand bond is necessary for transferring prestress force from the prestressing strands to the adjacent concrete. This paper proposes a new bond stress-slip model for 0.6 in. (15.2 mm), ...

An analytical model to predict strand slips within both transmission and anchorage lengths in pretensioned
prestressed concrete members is presented. This model has been derived from an experimental
research work by ...
