The　provisions　about　the　stability　capacity　of　a　member　with　the　slender　section　have　not　been　provided　in　Chinese　Code　for　Design　of　Steel　Structures　(GB50017-2003).　In　order　to　solve　this　problem,　in　this　paper,　the　classical　theory　analysis　was　reviewed　and　several　steel　design　codes　at　home　and　aboard　were　summarized.　Three　methodologies　such　as　effective　width　method　(EWM),　direct　strength　method　(DSM)　and　effective　section　method　(ESM),　were　emphasized　and　detailed　comparisons　among　them　were　presented.　Some　suggestions　for　further　research　topics　were　proposed　as　follows:　the　interactions　between　local　buckling　and　global　buckling,　the　distortion　buckling　of　cold　formed　steel　members,　how　to　control　width-to-thickness　ratio　of　components　and　plastic　hinges　of　members　efficiently　in　seismic　design,　and　general　principles　in　revising　the　Code　for　Design　of　Steel　Structures,　etc.　©　2016,　Editorial　Department　of　Journal　of　Beijing　University　of　Technology.　All　right　reserved.
