"It is well known that a building frame@ unrestrained against sidesway at the floor levels@ may buckle as a unit in the lateral direction when the applied load has reached a cerlain critical value. This phenomenon is often referred to as ""frame instability."" A great deal of research work has been done on this problem in the past@ and numerous methods are now available for obtaining exact and/or approximate solutions. This paper contains a general survey of the various frame instability theories@ discussions of several recent papers@ and a review of current and future research trends. A list of references and summaries of solutions for some practical frames are also included."
