A Proposal of Steel Structure Beam-to-Column Connection Appling High Strength Bolt Improved in Deformation Capacity

고력볼트의 변형능력을 향상시킨 강구조 보-기둥 접합부의 제안

This study propose cutting body portion-high strength bolts to improve deformation capacity of High strength bolts, which are the mechanical fasteners used for End-plate connection. And, we report that loading test results of steel beam-to-column connection using high deformation capacity-high strength bolts in accordance with SAC2000 loading program. As a result, the initial stiffness and the maximum strength of the connection using high deformation capacity-high strength bolts, are approximately the same in comparison with those of the end-plate connection using the existing high strength bolts. But the deformation capacity of the connection is more than twice as much as those.
