There is a reduction in the bearing capacity of a single stud and uneven distribution of shear force among the studs in the clustered shear studs of steel-concrete composite structures.Therefore,a type of shear stud cluster with a connector is proposed to further uniformize the shear force distribution between studs by setting connecting rods between the studs to improve the overall bearing capacity of the component.A push-out test and a finite ele-ment simulation are used to reveal the mechanism of the clustered shear studs with a connector,and a reasonable location of the connecting rods is given through a finite element parameter analysis.The results reveal that when the specimen reaches the ultimate bearing capacity,a reasonable connector setting can reduce the uneven distribution of shear force at the bottom of a stud by 83.76%and improve the bearing capacity by 8.56%.This study provides a theoretical basis for the structural optimization of clustered shear studs with a connector and promotes the develop-ment of new types of connectors.
