Abstract: In the calculation of structures in beams with spherical plain bearings (SBSPB) static bindings, movements are continuous, while rotations are staple to a node where a ball. is located in Dynamics, in several calculation codes, and mechanical frictions are often supposed to be neglected. In this paper, we proposed a modeling of the SBSPB which takes into account the friction during the SBSPB vibrations and also in the calculation of the degrees of freedom at the points of these structures. Hence, mathematics equations were established and their resolution by the modal method was proposed. Static analysis of the results showed that there is continuity of translations, and discontinuity of rotations in spherical nodes. In two dimensional dynamic approaches, the results obtained, are represented in the form of curves and their analysis emphasizes the influence of links bearings and viscous frictions during the vibration of the structure.
