This　paper　reviews　the　experimental　research　on　beam-to-column　connections　for　composite　special　moment　frames　(C-SMFs)　and　presents　an　experimental　database　consisting　of　165　tests　conducted　on　these　connections.　The　paper　also　summarizes　the　behavior　of　different　types　of　connections　and　evaluates　the　connections　using　current　standard　requirements　for　composite　beam-to-column　connections.　Based　on　the　evaluations,　double　split-tee　(DST)　connections　are　recommended　for　C-SMFs　with　rectangular　concrete-filled　steel　tube　(CFT)　columns,　through-beam　connections　are　recommended　for　C-SMFs　with　circular　CFT　columns,　while　connections　using　diaphragms　are　recommended　for　C-SMFs　with　both　rectangular　and　circular　CFT　columns.　Design　provisions　for　the　DST　and　through-beam　connections　are　also　provided,　which　include　design　equations　to　calculate　the　panel　zone　shear　strength　and　flowcharts　illustrating　step-by-step　design　procedures.　The　paper　will　be　useful　and　practical　for　engineers　planning　to　design　C-SMFs　using　current　AISC　seismic　guidelines.　(c)　2019　American　Society　of　Civil　Engineers.
