摘要：

In　order　to　study　on　seismic　performance　of　fiber　reinforced　polymer　confined　hollow　section　column　of　different　slenderness　ratio,　the　RC　rectangular　hollow　section　columns　with　slenderness　ratio　of　4　and　8　were　designed.　Quasi-static　test　was　carried　out　to　the　tested　columns,　and　the　failure　characteristic,　seismic　performance　and　additional　moment　were　analyzed.　The　experimental　result　shows　that　ultimate　lateral　displacement　of　FRP　confined　hollow　section　columns　with　slenderness　ration　of　8　is　increased　by　16%.　However,　the　maximal　lateral　force　and　ultimate　lateral　force　is　increased　about　5%;　pinch-shrinking　effect　of　confined　tested　column　with　slenderness　ration　of　4　is　reduced,　while　the　additional　moment　of　confined　tested　column　with　slenderness　ration　of　8　is　reduced.　Besides,　comparing　the　measured　lateral　force-displacement　of　the　top　of　tested　columns　and　rotation　deformation-moment　of　plastic　hinge　region　for　FRP　confined　columns　with　simulated　results,　it　is　shown　that　the　simulated　results　have　good　agreement　with　experimental　results.
