Abstract The aim of this paper is to propose the design criteria for plated beams with notches. A series of 8 specimens was tested to present structural performance and failure mode under 4 points bending. Three tentative design criteria are suggested for plated beams to ensure their full flexural capacity and ductility at failure; first, equivalent steel retio including the area of external plate should not be greater than 0.8 times max; second, the plate-width-to-thickness ratio should not be less than 50; the last, the neutral axis depth should not be greater than 0.52 times the effective depth. Tendency by first cracking load is certain as the thickness of external plate is increased.
