Traditionally, full strength moment resisting connections have been used in frames subjected to seismic loading to ensure plastic deformation of the connected member, resulting in dissipative zones due to the formation of plastic hinges. However analysis of recent seismic events has lead to an interest in alternative connection types in which plastic deformation can be controlled rather than prevented, thus allowing the frame to behave in a satisfactory predetermined manner. Such alternative connections include partial strength semi - rigid connections. Regardless of the connection type used an accurate prediction of the connections structural properties is paramount in determining the response of the frame. The structural properties can be determined directly by experiment or by semi empirical design rules that are based on test results. Alternatively a finite element model can be used to evaluate a connections structural properties. This paper discusses the capabilities of a finite element model to predict connection behaviour.
