摘要：

In reinforced concrete moment frames subjected to cyclic loading, the shear strength of beam-column joints is degraded as the lateral deformation increases. In the present study, design equations of the joint shear strength and hoop were developed for performance-based design of interior beam-column joints. The target drift ratio and bar bond parameters were considered to define the requirements of the joint shear strength and hoop strength. For verification, the proposed design method was applied to 50 existing interior beam-column joint specimens. The proposed method predicted the variance of the joint shear strength according to the target drift ratio. Further, the results of a parametric study were used to simplify the proposed method, and a modification of the current ACI 318 method was proposed for performance-based design.
