Abstract

PREFACE The current design criteria for cold-formed steel members published by the American Iron and Steel Institute (1986,1991) do not provide sufficient information for the design of web elements with openings. The primary objective of this investigation was to study the structural behavior of cold-formed steel C-sections with web openings. This study deals with the structural behavior of beam webs subjected to bending moment, shear force and combined bending moment and shear force. This report presents a summary of experimental study and findings of analytical results. The test results indicate that the current AISI Specification does not account for the behavior of C-section members with web openings. Design recommendations are proposed to predict the strength of cold-formed steel beams with web openings. This report is based on a thesis presented to the Faculty of the Graduate School of the University of Missouri-Rolla in partial fulfillment of the requirements for the degree of Doctor of Philosophy. This investigation was sponsored by the American Iron and Steel Insti tute (AISI) and Metal/Lath Steel Framing Association (MLSFA). The technical guidance was provided by the MLSFA-AISI Joint Task Force: J.E. Sullivan (chairman), C. Bissey, R.L. Brockenbrough, C.R. Clauer, E.R. diGirolamo, S.J. Errera, E.R. Estes, Jr., L. Hernandez, A.L. Johnson, K.H. Klippstein, J.P. Matsen, W.R. Midgley, T.B. Pekoz, N. Peterson, G.S. Ralph, R.M. Schuster, T.W. Trestain, and R.A. LaBoube. Thanks are also extended to R.B. Haws and K.L. Cole, AISI staff, and A.L. Sisco, MLSFA Staff, for their assistance.
