Grouting sleeves are widely used to connect precast concrete elements.Besides,the quality of grouting sleeves directly affects the overall performance of precast concrete structures.Thus,experiments,including unidirectional tension,high-stress repeated tension and compression,and large deformation repeated tension and compression,were conducted on multiple groups of semi-grouting sleeves to meet the requirements in codes of the performance of grouting sleeves.The results of the experiments reveal the performance of the semi-grouting sleeve with different diameters of connection rebars and the availability of the semi-grouting sleeve to be used as the connection in the precast concrete structures.
