Abstract: Mechanic studies realized on the two dimensional beams structures with swivel joints show that in statics, the vertical displacement is continuous, but the rotation is discontinuous at the node where there is a swivel joint. Moreover, in dynamics, many authors do not usually take into account the friction effect, modeling of these structures. We propose in this paper, a modeling of the beams structures with swivel joints which integrates viscosity effects in dynamics. Hence this work we will present the formulation of motion equations of such structures and the modal analysis method which is used to solve these equations.

Keywords: Beams, Swivel joint, Viscosity, Vibration, Modal Method.
