Abstract:
Requirements for mechanical properties of reinforcing bars are prescribed on the basis of bend tests and tension tests. Currently there are differing bend test provisions in the ACI Building Code and in the body of the ASTM A615 specification. This paper summarizes results of an extensive research program in which bend tests and tension tests were conducted on five sizes of Grade 60 reinforcing bars manufactured under the ASTM A615 specification. The research program was undertaken to aquire sufficant bendablity test data for establishing a common area of knowledge among the various groups preparing codes and reinforcing bar specifications, resolving the issue of differing bend test provisions.
