In this paper, we shall present one idea of the modelling of a beam element with a flexible sliding joint. The proposed element is composed of a 12-dof beam element and a 12-dof spring element. The spring element is coupled to the beam neutral line with the aid of a master slave technique. This technique yields system equations without algebraic constraints. In our model the sliding path is C1 -continuous between the element boundaries. The modelling is based on total Lagrangian finite element method. An example is presented in order to demonstrate the performance of the element.
