Abstract:
Title No. 55-51 presents an investigation of flexural bond in beams pre-tensioned with seven-wire strand of l/4, 3/8, and l/z in. diameter. Primary object was to clarify the factors affecting bond action and strength, and to study the influence of certain variables on strand slip. The principal factor investigated was variation of strand embedment length. The experimental results are discussed in detail, and criteria are presented for adequate design with respect to general bond slip of pretensioned strand. A hypothetical shape for the flexural bond stress wave immediately before bond slip is derived from the experimental results reported.
