摘要：

In this paper; based on previous experimental results, the buckling behavior of CFS channels beams with both edge and intermediate stiffeners in their web subjected to pure bending has been predicted with the aid of advanced numerical modelling. A non-linear finite element model has been developed to investigate the flexural behavior of CFS beams and to improve their moment capacities and observed failure modes at ultimate loads. Based on the analysis and optimization study, a numerical prediction relationship between web stiffeners and beam dimensions is developed.
