Abstract

Currently, the design of single angle members is governed by the LRFD Specification for Design of Single Angle Members (AISC, 2000). The provisions in this document are meant to augment the more general design provisions contained in the LRFD Specification for Structural Steel Buildings (AISC, 1999) for use with single angle members. The design provisions promulgated by the LRFD Specification for Design of Single Angle Members are the result of the best information available at the time of the preparation of the document in the early 1990s. Over the past decade, new information about single angle flexural response has accumulated from experimental and analytical research efforts aimed at more accurately quantifying the behavior of single angle beams. This new information is summarized herein and recommendations are made for rational single angle design provisions for consideration and possible inclusion in Chapter F of future AISC specification editions. An appendix of proposed Specification language is provided herein. The existing single angle specification provisions in the LRFD Specification for Design of Single Angle Members (AISC, 2000) require updating in order to reflect the current state of knowledge as it relates to flexural response. The current paper proposes new specification provisions that would supersede those currently promulgated by the LRFD Specification for Design of Single Angle Members (AISC, 2000). The new specifications are presented for consideration and possible use in Chapter F of new editions of the AISC Specification. The paper has described the rationale behind these new provisions and in a sense serves as a commentary on them.
