Abstract

Ductility parameters defined in the second progress report were previously obtained by conducting tension coupon tests on specially produced A and S steels. In this report, tension coupon test results are presented for a 20 gage commercial low ductility steel, i.e. an ASTM Grade E steel, herein designated as steel B. Its behavior is compared with that of the specially rolled A and S steels to test the validity of conclusions arrived at in the second progress report. Test programs were set up to study the behavior of B steel under static tension loading, one program for single bolted connections and another for rectangular plates with holes. Here again the behavior of B steel is compared with A and S steels. A few connection tests were conducted on fully annealed A steel specimens to compare their behavior with low ductility A steel specimens. In Appendix B the processing and metallurgical history for A, B and S steels is given.
