Civil Engineering Study 97-4
This Fourth Progress Report presents the results of 56 connection tests conducted at the University of Missouri-Rolla during February-April, 1997. The intent of this limited test program was to gain an understanding of the general behavior characteristics of connections in grade 80 steels. No attempt was made to develop an indepth understanding of the connection behavior, which would be necessary to propose complete or comprehensive design recommendations. The performance and behavior of screw and welded connections in low-ductility steel were studied by testing to failure 36 specimens using self-drilling screws, 16 welded connections using either transverse or longitudinal fillet welds, and 4 connections using resistance welds. The material used in this study consisted of ASTM A653 Structural Grade 80 Steel (formerly ASTM A446 Grade E). Test results were compared with the recently approved AISI Specification (1), and other recently published research results (2).
