Experimental study on hysteretic characteristic of precasted concrete frame joints with steel giber high strength concrete

LIU Hai-feng~1,ZHAO Bin~2(1.Qinghai Architectural Professional Technology Collgeg,Xinning 810012,China;2.Research Institute of Structural Engineering and Disaster Reduction,Tongji University,Shanghai 200092,China)  
By comparing experimental research on the three types of full-scale models:monolithic joints with high strength concrete,concrete and steel-fiber filled precast high strength concrete joints under low reversed cyclic loading.The results indicate that partial stirrups can be saved by using of steel fiber concrete to cast the joints of precast concrete structures,which may facilitate casting concrete.Moreover,the steel fiber in joints can dramatically improve tensile strength and ductility of concrete herein as well as reduce bond-slip of bar and easily come into being elastic joint.
