Civil Engineering Study 99-1
PREFACE Fatigue in a structural steel member or connection is the process of initiation and subsequent growth of a crack under the action of a cyclic or repetitive load. The fatigue process commonly occurs at a stress level less than the static failure condition. Although fatigue design guidelines have existed for hot-rolled steel structural members and connection, there have been no generally accepted design guidelines in the AISI Specification for addressing fatigue in a cold-formed steel member or connection. Therefore, the intent of the research reported herein was to develop general design rules for design of cold-formed steel members and connections subject to fatigue loading. The fatigue design recommendations developed and reported herein are based on a review of available test data. No additional experimental studies were performed to support the suggested design recommendations. This study was made possible by the funding provided by the American Iron and Steel Institute. The AISI General Provisions Subcommittee (J. M. Fisher, Chairman) provided technical guidance for the study.
