NUMERICAL EVALUATION OF THE DISTORTIONAL-GLOBAL INTERACTION PHENOMENON IN COLD-FORMED STEEL HAT-SECTION BEAMS UNDER NON-UNIFORM BENDING
Cold-formed steel profiles exhibit high structural efficiency; however, their reduced thickness renders them highly susceptible to interaction between buckling modes, particularly distortional and global modes. This work investigates the behavior of hat-section beams subjected to uniform and non-uniform bending, a load...
