Steel-concrete　composite　structure　is　one　of　the　main　structures　in　civil　engineering　construction.　In　bridge　engineering,　composite　members　can　be　classified　into　three　types　according　to　the　basic　bearing　behavior,　i.　e.,　composite　beam,　composite　column　and　composite　arch.　In　this　paper,　the　main　structure　forms　and　general　application　of　steel-concrete　composite　bridges　in　China　are　described;　the　research　development　and　engineering　application　of　the　new　composite　structure　types　presented　in　recent　years　are　focused　on.　The　traditional　steel-concrete　composite　bridges,　such　as　the　shaped　steel-concrete　slab　composite　girder,　the　PC　box　girder　with　corrugated　steel　webs　and　concrete　filled　steel　tube　arch,　have　been　widely　used　and　their　specification　system　has　been　established　by　far.　In　the　future,　the　application　experience　should　be　constantly　summed　up　so　as　to　further　improve　the　specifications.　At　the　same　time,　it　is　necessary　to　track　closely　the　latest　international　trends　and　carry　out　innovative　research.　The　research　and　development　of　new　composite　bridge　have　become　very　active　in　our　country　in　recent　years.　Many　new　types　of　steel-concrete　composite　bridge　structures　were　developed,　such　as　the　deck　slab　with　stiffened　scaffolding　and　CFST　composite　truss,　corrugated　steel　web-CFST　composite　beam,　CFST　stiffened　scaffolding　composite　columns,　CFST　main　members　with　reinforced　connection　members　composite　columns　and　hybrid　columns　and　steel　webs　(bars)-concrete　arch　bridge.　Some　of　them　have　been　used　in　few　engineering　projects,　while　others　have　not　been　used.　In　the　future,　it　is　important　to　strengthen　their　application　and　popularization,　conduct　application　technology　research　on　the　engineering　practice　requirement,　form　application　guide　or　technical　standards,　and　make　contribution　to　the　development　of　the　composite　structures　and　technical　progress　of　bridge　engineering.
