Generally swivel joints often frameworks, notably beams one, and allow them to swivel in a point around the three space dimensions. In the modeling of those frameworks, swivel joint is supposed to be in a node. Between two elements at a node where there is a swivel joint, displacements are continuous and rotations are not. This paper is a contribution to the calculation of the rotations in a swivel point. Our calculation method is based on the finite elements method and the disturbance of the elementary stiffness matrix through the static condensation. At the end, we present analytical results obtained on the connected elements by moving the swivel joint from one element to another and the proposition to put simultaneously two swivel joint in two related elements.
