Abstract: The strength, ductility, and energy dissipation capacity of thin-walled, stiffened rectangular concrete-filled steel columns (thin-walled stiffened RCFT columns) subjected to cyclic loads are significantly upgraded by ...

Abstract: The strength and ductility of thin-walled steel columns under cyclic loads are considerably upgraded by filling concrete into hollow spaces surrounded by steel tube and diaphragms. The above thin-walled steel columns filled ...
