초록

In this research, the development length of headed bar and the transverse reinforcement ratio of the beam column joint on the seismic behavior of exterior beam column joints was experimentally investigated. Four beam column joints specimens were tested with the large dimeter headed bars. The variables for this study were the side clear cover thickness, transverse reinforcement ratio and failure type. The test results showed enough anchorage capacity of large diameter headed bars and ductile behavior of exterior beam column joints.
