<br />
In this work a mathematical model based on the lumped damage mechanics is developed. The model allows predicting the damage evolution on steel hollows structural beams subjected to biaxial bending. The most significant phenomenon in this case is the appearance and development of the local buckling. In order to describe this process, it is admitted that the inelastic phenomena can be concentrated in plastic hinges. It is introduced then a damage variable that can take values between zero and one that characterizes the level of local buckling in the structural member. The damage evolution is described by the introduction of local buckling domain that can be compared to the elastic domain used in the conventional theory of plasticity. The model is validated by numerical simulation of experimental tests carried out in the Structural Mechanics Laboratory at the Centroccidental Lisandro Alvarado University.
