George Morcous, Kromel Hanna, and Maher K. Tadros, University of Nebraska-Lincoln For several years, 0.7-in. (17.8-mm) diameter strands have been used in cable-stayed bridges and mining applications in the United States, and for post-tensioning tendons in Europe and Japan. To
Henry G. Russell, Henry G. Russell, Inc. The accuracy of predicting camber and prestress losses in long-span bridges can be improved when measured values of concrete material properties are used. This article describes the ASTM test for modulus of elasticity
