THE EXPERIMENTAL RESULTS WERE USED TO CONFIRM THE VALIDITY OF THE LUMPED DAMAGE MECHANICAL APPROACH TO MODEL THE POST-LOCAL BUCKLING STRUCTURAL BEHAVIOR. IN THIS APPROACH LOCAL BUCKLING IS LUMPED AT PLASTIC HINGES. THE DEGREE OF LOCAL BUCKLING IS REPRESENTED BY A VECTOR DAMAGE VARIABLE. IT IS DESCRIBED THE IMPLEMENTATION OF THE MODEL IN A FINITE ELEMENT PROGRAM.enBucklingStructural engineeringFinite element methodHingeMaterials scienceEngineeringarticle
