The design criteria for SRC T-shaped and L-shaped beam-column joints utilizing mechanical anchorages are proposed. The design criteria are based on the formulation of the joint shear force demand at the ultimate strength of SRC beam or column bending as well as the joint shear force capacity. The specific features of the formulations include: (1)the influence of the variation of axial force in the beam on the joint force demand is considered for SRC L-shaped joint, similar to RC L-shaped joint proposed previously, (2)the influences of anchorage length of reinforcement and steel member on the joint concrete strength are considered in the formulation of the joint shear force capacity, similar to SRC exterior joint proposed previously. Proposed design criteria are verified through the experimental data on the 6 specimens of T-shaped and L-shaped beam-column joints.
