The present paper presents an innovative approach to connect one-/two-dimensional models using a unified formulation with node-dependent kinematic capabilities. These models can use a different kinematics approximation at each node of the element. Carrera Unified Formulation has been used to derive the governing equations in a compact and general form. The possibility to connect one- and two-dimensional elements, and eventually to refine the kinematic model locally, has lead to a general reduction of the computational costs guaranteeing the same numerical accuracy.
