역타공법에 적합한 Y형 플레이트 형식 CFT기둥-H형강보 접합부의 구조성능평가

초록

Recently, problems of adjacent buildings settlement, dust and noise arose from dense urban construction work. In order to solve thisproblem, a variety of Top-down method was used in urban construction work. In this study, new Top-down method was developed toimprove the performance of urban construction and new detail of CFT column - H shape steel beam connection with Y type plate wasproposed. The performance evaluation was performed with the proposed detail. Four specimens was made with introduction of structuraldiaphragm design concept. Test was performed to evaluate the parameter of Y type plate and to confirm the safety of proposeddetail. Also, the test result of proposed detail was classified by performance evaluation criteria of connection in Eurocode3.
