Resumen
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 behavior analysis by measuring the force supported by the prestressing strand on a series
of specimens with different embedment lengths has been used. Relationships between the average
bond stress for both the transmission length and anchorage length as a function of the concrete compressive
strength have been found. Equations to compute transmission and anchorage lengths of 13 mm prestressing
strands have been obtained. The experimental results have been compared with the theoretical
prediction from proposed equations in the literature and with experimental results from other authors.
