Abstract:
The relations (force in the reinforcement) vs. (slip of the reinforcement in both extremes of the specimen) during the release on groups of specimens with different embedment lengths have been analyzed. Both sequences of slip values adopt a bilinear form, a descending branch with a growing embedment lengths and a horizontal branch corresponding to the cases of embedment length equal or greater than the transmission length. Therefore, both sequences of slip values permit to establish two new criteria to determine experimentally the transmission length.
