The effect of a number of variables upon prestress anchorage length was investigated. The end zones of prestressed pretensioned concrete members were simulated by casting against steel bulkheads. 3/8" diameter strands and .276" diameter wires were used. Fifty specimens were tested. The variables investigated were; surface condition of prestressing steel, speed of release of prestress, water/cement ratio of concrete, age of concrete, stress in concrete, and vibration.
A relationship between free end pull-in and anchorage length was found and is compared with the results of other investigators. / Applied Science, Faculty of / Civil Engineering, Department of / Graduate
