Experimental Study on Anchorage Performance of Steel Bars with FRP Confined Rings
In order to study the performance of reinforcement anchorage connection with FRP restrained ring,static tensile tests were carried out on 66 specimens,The main parameters considered in the test such as the diameter of steel bars,the diameter and thickness of the restraint ring,the strength of concrete and the length of anchorage.The result shows that the anchorage performance of the steel bar can still be guaranteed even if the anchorage length reaches 0.8la,There is no slip and local destruction phenomenon between FRP restraint ring and internal grouting material and peripheral concrete.The study conclusions also indirectly prove that the proposed technique is a reinforcement connection method for fabricated concrete structures with many good performances including the reliable performance,simple construction process and good economic benefit,which is suitable for construction industrialization of prefabricated reinforced concrete structures.
