Abstract

Metal braced frames show two kinds of instability, the first related to the instability of a single beam-column pinned at its joints (Euler's problem) and the second to the side-sway of the whole frame. In this paper a simple two d.o.f. system is proposed to model one storey of a frame. It shows two uncoupled critical loads which depend upon the elastic and geometric properties of the structure. The coupled instability is considered and the different kinds of postcritical behaviour are shown. A relationship between the geometric parameters, which determines the coupled instability, is given. © 1994.
