000004784 520__ $$2eng$$aMechanical joints can have a significant effect upon structural response, causing localized nonlinear stiffness and damping changes. As many structures are assemblies, incorporating the effects of joints is necessary to produce predictive finite element models. In this paper, we present an adjusted Iwan beam element (AIBE) for non-linear dynamic response analysis of beam structures containing joints. The adjusted Iwan model consists of a combination of springs and frictional sliders that exhibits nonlinear, hysteretic behavior due to the stick-slip behavior of the sliders. The beam element consists of two adjusted Iwan models arranged to correspond to the usual arrangement of degrees-of-freedom, transverse displacement and rotation at each of the two nodes. The resulting element requires six parameters, which need to be initially determined. The parameter identification constitutes an inverse problem that will be discussed in a later paper. By using AIBE, a nonlinear dynamic response analysis is implemented for a beam structure with a bolted joint. The effectiveness of AIBE is assessed by comparing the numerical solution with experimental measurement.
