STRENGTHENING OF SHORT STEEL COLUMN WITH CFRP AFTER LOCAL BUCKLING

摘要：

　　In recent years,as a repairing method for corroded steel members,a method bonding carbon fiber sheets(CFRP)with resin to the steel members has been applied.Under operation,there are cases that the steel members are subjected to deformation included by earthquake,clashing or conflagration.Therefore,this study investigated the strengthening effect of CFRP bonding for a short steel column after local buckling toward an emergency repair.Firstly,out-of-plane deformation was introduced to short steel columns by uniaxial compression.And then,after strengthening by CFRP,a compressive test was conducted.As a result,the strength of damaged steel columns recovered up to the strength of an undamaged column owing to CFRP bonding.
