Abstract:
The author outlines methods and results of creep tests performed on three different samples of steel wire under constant specimens prestressd by use of these same wires is described. Load tests on these spcimens and non-prestressed concrete are compared and the differences in deformation are attributed to the combined creep of steel and concrete. Results of creep tests on steel alone are applied in order to ascertain creep of concrete alone. Concrete shrinkage, steel strains, and steel and concrete creep are considered in recommending an anticiopated percentage loss of prestress for design puropses.
