GENERAL Cold-formed steel wall studs are widely used in the U. S. and Canada. The 1980 A.I.S.I Specification (Ref. 1) contains provisions for the design of such wall studs based primarily on the research conducted at Cornell University (Refs. 2 and 3). This research involved theoretical and experimental studies on wall studs subjected axial loads only. The Specification provisions on the case of combined axial and lateral loading were derived intuitively and were made intentionally conservative. The excessive conservatism in the provisions for the combined loading case prevents using wall studs as economically as possible. The primary objective of the tests reported herein was to provide experimental evidence to assess the degree of conservatism in the present approach and to formulate a program for future studies. This study was not intended to result in conclusive design recommendations. The secondary objective of the study was to explore the behavior of 16 foot long wall studs that are 6 inches deep. Such applications are more common now than when the original research was conducted. The previous work was on 4 inch deep and 8 foot long wall studs.
