The　current　AISC　Specification　(AISC　360-16)　specifies　the　material　strength　limits　for　concrete-filled　steel　tube　(CFT)　columns.　According　to　AISC　360-16,　the　steel　yield　stress　(F-y)　for　CFT　columns　should　not　exceed　525　MPa,　and　the　concrete　compressive　strength　(f＇(c))　should　not　exceed　70　MPa.　CFT　columns　are　classified　as　high　strength　if　either　F-y　or　f＇(c)　exceeds　these　specified　limits,　and　are　classified　as　conventional　strength　if　both　F-y　and　f＇(c)　are　less　than　or　equal　to　the　limits.　Due　to　lack　of　adequate　research　and　comprehensive　design　equations,　AISC　360-16　does　not　endorse　the　use　of　high-strength　materials　for　CFT　columns.　This　paper　makes　a　contribution　towards　addressing　this　gap　using　a　two-step　approach.　The　first　step　consists　of　compiling　an　experimental　database　of　high-strength　rectangular　CFT　column　tests　in　the　literature　and　evaluating　the　possibility　of　extending　the　current　AISC　360-16　design　equations　to　high-strength　rectangular　CFT　columns.　The　second　step　consists　of　developing　and　benchmarking　detailed　3D　nonlinear　finite　element　models　for　predicting　the　behavior　of　high-strength　CFT　columns　from　the　database.　The　benchmarked　models　are　being　used　to　perform　comprehensive　parametric　studies　to　address　gaps　in　the　database　and　propose　design　equations　for　high-strength　rectangular　CFT　members,　which　will　be　part　of　a　future　paper.
