| Abstract: | Epoxy resin coated bar can prevent steel bar from rust and has been applicated for durability design of reinforced concrete structure. Anchorage-bond properties of epoxy resin coated bar are weakened because of the change of surface in rebars. Based on pull-out bond tests and beam anchorage experiments, the paper discusses the bond-anchorage mechanism, properties and strength. Then the design of anchoring length by reliability analysis is proposed. |
