To　effectively　protect　Chinese　ancient　timber　buildings,　CFRP　(Carbon　Fiber　Reinforced　Plastic)　sheet　was　considered　for　strengthening　by　Dunjie　means.　An　eave　column　in　the　Forbidden　City　was　taken　as　example,　its　1　2　scale　models　were　built,　including　1　intact　model　and　5　CFRP-Dunjie　strengthened　models.　Axial　compression　experiments　were　carried　out.　Parameters　such　as　curves　of　force-displacement,　curves　of　force-strain,　ultimate　compressive　strength,　ductility,　vertical　stiffness　and　so　on　of　the　models　were　obtained.　Strengthening　effects　of　CFRP　sheets　were　also　discussed.　Results　show　that　compared　to　the　intact　model,　axial　compression　strength　of　the　CFRP　strengthened　models　can　improve　about　0.2%~8.3%.　Their　compressive　strain　can　also　be　restored　109.6%~126.5%　in　ring　direction,　108.6%~160.7%　in　lengthwise　direction.　Ductility　and　axial　compression　stiffness　values　of　the　strengthened　models　are　larger　than　that　of　the　intact　model　during　their　destruction　stage　under　loads.　Stiffness　degradation　of　all　strengthened　models　is　not　obvious.　Thus　CFRP　sheet　has　good　effects　for　strengthening　timber　columns　with　decay　roots　by　Dunjie　means.　©　2016,　Editorial　Office　of　Journal　of　Building　Structures.　All　right　reserved.
