Analysis and design of steel frames with semi-rigid connections

Frans Bijlaard, David Anderson, David A. Nethercot
A survey is given of methods of analysis for steel frames with semi-rigid connections. Various models are employed to represent the behaviour of the Joint, the most common being relationships between moment and rotation based on experimental behaviour. The results of such analyses may be used as a basis for design. This approach has been found to be well-defined for braced frames using plastic theory, but for other cases reliance is placed at present on empirical methods. Research needed to

Pour traduire le comportement des assemblages, divers modeles peuvent etre utilises. Le plus courant de ceux-ci repose sur des relations moment-rotation relevees lors d'essais. Les resultats de telles analyses peuvent servirde base de dimensionnement. Cette approche se revele adequate pour les structures contreventees calculees selon la theorie plastique; par contre, pour les autres cas, on continue ä se fonder sur des methodes empinques. On met enfin en evidence les recherches encore necessaires pour pouvoir degager des approches plus rationnelles et on resume l'etat des connaissances actuelles.
