An experimental investigation to determine the transfer length of a seven-wire prestressing
strand in different concretes is presented in this paper. A testing technique based on the analysis of bond
behaviour by means ...
This paper presents an experimental research work to determine both the transmission and the anchorage
lengths of seven-wire prestressing steel strands in different concrete mixes. A testing technique
based on a bond ...

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 ...
