An　experimental　investigation　into　the　seismic　behavior　of　composite　concrete-filled　rectangular　steel　tubular　column　with　steel　beam　was　conducted.　Two　kinds　of　connections,　namely　bolted　flange　plate　(BFP)　connection　and　welded　flange　plate-bolted　web　(WFP-BW)　connection,　were　tested　under　reversed　low　cyclic　loading　at　the　ends　of　columns.　This　paper　presents　the　relationships　between　force　and　displacement　at　the　end　of　column,　the　relationships　between　the　moment　and　rotation　of　the　joints,　degradations　of　strength　and　stiffness,　ductility　ratio　and　energy　dissipation　ratio,　failure　mechanism　and　failure　characteristics　of　these　two　connections,　and　compares　them　with　that　of　the　welded　flange　plate　(WFP)　connections　under　different　axial-compression　ratios.　Some　valuable　conclusions　are　drawn　from　the　comparisons.
