Abstract
PREFACE When considering the web crippling strength of a cold-formed steel member, the current edition of the AISI Specification for the Design of Cold-Formed Steel Structural Members does not distinguish between the behavior of a member having its flanges attached to a support member, and a member not attached to its support. To enhance the industry and design professional's understanding of web crippling, a pilot study was initiated at the University of Missouri-Rolla to explore the influence of flange attachment. The financial assistance for this research was provided by the Metal Building Manufacturers Association (MBMA) and the American Iron and Steel Institute (AISI). This research consisted of 52 web crippling tests on identical specimens, 26 specimens were bolted to a support beam and 26 were not attached to the support beam. This enabled direct comparison and evaluation of flange attachment. The results were compared with two design criteria, i.e., the 1986 AISI Specification and the 1986 Automotive Steel Design Manual. Because this was a pilot study, there are no new design recommendations, however, suggestions are proposed for future study. This report is based on the thesis presented to the Faculty of the Graduate School of the University of Missouri-Rolla (UMR) in partial fulfillment of the requirements for the degree of Masters of Science in Civil Engineering. This investigation was sponsored by the Metal Building Manufacturer's Association (MBMA) and the American Iron and Steel Institute (AISI). The technical guidance provided by the AISI Subcommittee on Flexural Members and the AISI Staff is gratefully acknowledged. Members of the AISI Subcommittee are: J. N. Nunnery (chairman), R. E. Albrecht, R. E. Brown, D. S. Ellifritt, E. R. Estes, Jr., T. V. Galambos, M. Golovin, R B. Heagler, D. L. Johnson, K. H. Klippstein, R. A. LaBoube, J. N. Macadam, T. B. Pekoz, R. M. Schuster, T. W. Trestain, and W. W. Yu. The AISI Staff include R. B. Haws and K. L. Cole. Thanks are also extended to G. S. Harris of the Metal Building Manufacturers Association for his assistance. Appreciation is also expressed to Shannon Hopkins, Greg Schulte, Jeff Lambert, Scott Fletcher and the staff of the Civil Engineering Department for their valuable assistance in the preparation and performance of the tests.
