“…There is reasonably good agreement between the observed and predicted moment-rotation behaviour, with the model providing a slightly conservative prediction of Mb. These more detailed results confirm the observations initially made in a discussion of the Kriviak-Kennedy paper by MacIntyre and Van Dalen (1987) in which the good agreement between the Kriviak-Kennedy model and the unclipped end plates tested at Queen's was noted.…”

The rotational behaviour of clipped end plate connections was studied by subjecting nine clipped and three conventional or ''unclipped" specimens with varying connection geometry to combined shear and moment and obtaining the corresponding moment-rotation characteristics. It was found that thc clipped end plate connections in this investigation had more than adequate rotation capacity to permit an interior beam connected to a supporting member by this type of connection to achieve its full plastic moment, provided the length-to-depth ratio of the beam does not exceed 20. For the range of rotations that would be cxperienced by clipped end plate connections in a practical structure, a model originally developed to predict the moment-rotation behaviour of conventional shear end plate connections was modified so as to be applicable to clipped end plate connections. Good agreement was obtained between the test values and those predicted by the modified model. No adverse effect on the rotational behaviour of the connections was observed to result from the asymmetry caused by clipping the end plate.Le comportement des assemblages de plaque d'appui agrafCs soumis ii la rotation a CtC analysC en soumettant neuf Cchantillons agrafks ettrois tchantillons traditionnelsde gComCtrie diverse au cisaillement et au moment flCchissant afin d'obtenir les carac-tCristiques moment-rotation correspondants.
