Repair of post-heated short rectangular reinforced concrete columns with FRP jackets

The residual strength and stiffness of concrete columns are decreased when exposed to elevated temperatures. This study proposes an external confinement provided by fiber-reinforced polymer (FRP) rehabilitate deficiencies that originate from fire damage. Recent studies show the efficiency this strategy is a function column cross-section geometry number FRP sheet layers applied. current investigates repair post-heated short rectangular RC (SRRC) with jackets. Rectangular heat-damaged wrapped one or two carbon (CFRP) glass (GFRP). experimental results indicate ultimate axial load capacity columns, repaired was improved considerable level unheated columns. Moreover, it found pseudo-ductility energy dissipation CFRP jackets larger than those
