Creep in Prestressed Concrete Piles
The results of loading 55-feet long, 16-1/2 inch octagonal, prestressed concrete piles are presented in the report. Time dependent deformations were measured for superimposed loads of 100 tons and 200 tons and for prestress without any superimposed loads. The piles were placed in a horizontal position and prestress cables were used to apply the compressive axial loads. Strain measurements were taken along three longitudinal segments of the pile. In general, the creep strain was small for the steam-cured prestressed concrete piles. The data showed some sensitivity to age of loading and indicated that less creep occurs when loaded at a later age. The data also indicated a linear dependence of creep strain to applied stress.
