Abstract:Discusses an investigation of the essential features of partial prestressing. Static and fatigue tests as well as routine acceptance tests are described. A few of the conclusions drawn are: (1) Cracks should not form in acceptance tests under bending tensile stress of 750 to 800 psi for pre-tensioned wires or 650 psi for post-tensioned wires. (2) In the former case no cracks should form under fatigue loading corresponding to a bending tensile stress of 650 psi. (3) When cracks have occurred and fatigue loading takes place, up to a bending tensile stress of 650 psi, the cracks disappear on removal of the load and no noticeable deformation remains. (5) Several million repetitions of the fatigue load do not, affect the subsequent static failure load.
