접합부의 모멘트-회전각 함수식을 제안하는 데는 충분한 실험결과를 바탕으로 행해져야 하나 실험결과 수집의 어려움뿐만 아니라 충분하지 못한 실정이다. 따라서 본 연구에서는 먼저 국내에서 진행된 실험결과를 수집하고, 이를 유한요소해석을 통하여 검증하고 변수에 따른 해석을 확장하였다. 유한요소해석으로부터 얻은 데이터를 회귀분석을 통해 접합부의 모멘트-회전각 함수를 제안하고자 한다. |

The conventional analysis methods are performed using the assumption that the connections are either fully rigid or ideally pinned. Thus, it cannot predict exactly the performance of overall frames because all connections have some rotational rigidity. Many researchers studied bolted connections with assuming as semi-rigid and welded connections as rigid. Although there are many structural merits of the Concrete Filled Tube(CFT) columns, it is very difficult not only to manufacture connections but also to understand exact behavior of CFT Column-to-Beam connections. This paper is focused on the connections between CFT column and steel beams reinforced with exterior plate diaphragms. These connections perform flexibly comparing to exiting interior and exterior diaphragm connection types due to out-of-plane deformations of the column flange at the tension side under the bending moment. The main purpose of this study is to derive a function of the moment-rotation curve for the connections. Although the function should be derived based on sufficient experimental results, there are not many test results of Column-to-Beam connections. Therefore, it is needed to utilize the analytical method by using a finite element analysis program ANSYS. The analysis models are constructed based on the existing test specimens and additional models are made to compensate for the insufficient test results. The proposed equations of connections can predict moment-rotation relationships of connections and the flexibility of connections make different overall frame performance. |
