Fundamental steps of the discretization of frames by fi nite elements
• Intersections between beams and columns;
• Points where abrupt changes in the geometry occur;
• Free - standing ends of cantilever elements;
• Points of application of concentrated actions (forces and moments) or imposed deformations;
• Points where output quantities are required.
