USE OF APPROXIMATE ENGINEERING METHODS FOR SEMI-RIGID FRAME ANALYSIS

Abstract

This paper gives a short summary about the possibilities of constructing more precise, but not too difficult connection models for frame analysis. It is dealing with simple methods, which can be useful tools for - either to construct envelope curves for the elastic and for the plastic behaviour separately, - or to determine the elastic - plastic response of the frame by concentrating all of non-linearities into real or pseudo connection springs, which are connecting the elastic members.
