Abstract Pore-forming grouted connection characterized with great economic superiorities and application potentials has weaker mechanical properties comparing to the steel sleeve grouted connector. To improve the mechanical properties of pore-forming grouted connector, the NPGCS was generated using welded closure confinement steels in buckle configuration. Experimental tests and finial element analysis of two NPGCS precast shear wall specimens and one cast-in-situ shear wall specimen was carried out to test mechanical performances. Results indicated that the mechanical properties of NPGCS can match the connection requirements even under the adverse effects from grouted interface gap opening and slip. Contributing to the excessive confinement steels, the mechanical properties of NPGCS specimens are better than that of the cast-in-situ specimen. So, according to the suggestions given out in this paper, the NPGCS can be widely applied into precast buildings in certain areas and conditions.
