강재기둥-PHC 파일 간 반구형 접합부(HAT Joint)의 볼트 연결에 대한 구조성능평가 = Structural Performance Evaluation of Bolt Connection for Half-sphere Joint between PHC Pile and Steel Column

다국어 초록 (Multilingual Abstract)

To overcome the weakness of spread foundation in large space structure, the research of precast pile for replace spread foundation have been conducted. The new type of joint between PHC pile and steel column is named HAT Joint(Hollow hAlf-sphere cast-sTeel Joint). It connected PHC Pile by bolt that verification of bolt connection should be accomplished. In this paper, pull-out test and flexural performance for HAT Joint to verifying the bolt connection is explained. As a result, the pull-out and flexural capacities of bolt were checked to use in real structure. Furthermore, the equation of pull-out strength was proposed.
