초록

초고층 빌딩의 수요가 증가함에 따라 고강도 강관의 수요 또한 함께 증가하고 있다. 이에 고강도 고인성의 600MPa급 강관의 접합부 내력 연구가 필요하게 되었다. 또한 현행국내기준에는 강관의 경우 항복응력 360MPa 이하에 설계식을 적용하도록 되어 있다. 즉, 고강도강재를 이용한 600MPa 강관의 경우 현행기준을 적용할 수 없으므로 600MPa급 고강도 강관의 거셋플레이트 접합부의 내력실험 및 유한요소해석을 통하여 기존 설계식의 적용가능성을 조사하고 접합부의 거동을 연구하고자 한다. 특히, 본 논문에서는 원형강관에 길이 방향으로 거셋플레이트가 접합된 접합부에 횡력(수평력)이 작용하였을 때의 거동을 다루었다. 유한요소해석 및 실험결과를 설계식과 비교해보면, 고강도 강재에서는 기존의 설계식들이 56~79%로 과소평가되었다.

With the increase in the demand for high-rise buildings, the use of high-strength steel has likewise increased. Thus, it has become more necessary to study the resistance force of the high-strength hollow structural section (HSS) joint of 600MPa. Additionally, the current design equation in Korea limits maximum yield stress at 360MPa in the case of HSS. In other words, since the current specification does not apply to HSS of 600MPa, this study aims to investigate the applicability of design equations as well as examine the behavior of the connection through the experiment and finite element analysis (FEA) of the plate-tube connection of 600MPa. In particular, this paper presents the behavior of joints with the gusset plates welded in the longitudinal direction of the circular hollow section (CHS) when the joints are subjected to lateral force. Comparing design equations with the results of FEA and the test, existing design equations are underestimated to be 56~79% in the case of high-strength materials.
