Abstract
This paper discusses the results of an experimental investigation conducted on seven ASTM A 36 steel members subjected to axial tension. The members were chosen with various ratios of net cross-sectional area A_n to gross cross-sectional area A_g. The specimens were subjected to incremental axial displacement until fracture to determine the displacement ductility of each specimen. The results of this study showed that the displacement ductility is highly dependent on the ratio A_n/A_g and the geometrical shape of the member. It was also found if the ratio A_n/A_g is less than the specified yield stress to ultimate strength F_y/F_u, the displacement ductility will be close to 1, which means the member will fail in a brittle manner.
