In order to study the shear behavior of studs embedded in engineered cementitious composites (ECC), model tests and the numerical analysis of finite elements were carried out. The failure mode of studs embedded in ECC was determined based on push-out model tests. Then, parametric numerical analysis of finite element was performed to elucidate the effects of stud diameter, height/diameter ratio of stud, tensile strength of stud, and compressive strength of ECC on the shear behavior and failure mode of connectors. Finally, a method for calculating the shear capacity of studs embedded in ECC was established according to the above research. The results show that the shear strength of studs embedded in ECC is closely related to the failure mode of the push-out model. When the push-out model fails due to ECC crushing, the shear strength of the connector depends on the compressive properties of ECC. When the push-out model fails due to stud fracture, the shear strength of the connector depends on the tensile strength of the stud and compressive properties of ECC; increasing the compressive strength of ECC and reducing the height/diameter ratio of the stud both can improve the shear stiffness of the connector, but the tensile strength of the stud has a slight effect on the shear stiffness of the connector. When the height/diameter ratio of the stud is lower than 4.60, the shear strength of the stud reduces with the decreasing height/diameter ratio of the stud. Studs with a height/diameter ratio of greater than 4.60 are recommended to serve as a shear connector applied in steel-ECC bridge decks.
