To improve the convenience of grouting sleeve construction and explore its mechanical properties,a newly grouted sleeve lapping connector that two overlapped bars were placed,clinging to the wall of a hollow cylindrical standard steel pipe and anchored by high strength grout,was put forward.16 specimens varied in lap length were tested under tensile load.The failure mode,load displacement curve,ductility and hoop strain of sleeve were discussed.Based on the experimental results and plane section assumption,mechanical property analysis of grouted sleeve lapping connector were conducted.The relationship of sleeve hoop strain varying with lap length was studied.The lapping length is greatly reduced due to sleeve constraint.Because of sleeve deflection,the rigidity and ductility of the specimen are smaller than that of the corresponding steel.The tension in the middle of the lapping connector and the shear transferred through grout to sleeve are smaller than that in butting connector，so there is a lower requirement in anti-pull property of sleeve and bond property between grout and sleeve.When the sleeve length is short,slip in the interface of steel and grout increases the tension of middle steel,thus the resultant force of the sleeve and grout is pressure,on the contrary,the resultant force is tensile force.As the lap length increases,the maximum hoop compressive strain increases in the middle of the sleeve during the loading process.At ultimate load,as the lap length increases,the hoop tensile strain of the sleeve decreases.
