Abstract

The purpose of this study is to investigate the ultimate strength and curling influence using finite element analysis based on the previous test results of ferritic stainless steel bolted connections. Results obtained from finite element analysis (FEA) were compared with those of test results and the validity of numerical modeling was verified. The conditions of curing occurrence for edge/end distance were investigated and ultimate strength reduction ratio caused by curling was estimated quantitatively. Moreover, the ultimate behaviors such as fracture mode and ultimate strength by FEA were compared with those predicted by current design specifications such as AISC, KBC2009, AIJ and AISI.

본 연구는 페라이트계 스테인리스강 일면전단 볼트접합부의 구조거동에 관한 기존실험연구를 바탕으로 유한요소해석법을 이용하여 접합부의 최대내력과 면외변형에 대해 조사하는 것을 목적으로 한다. 유한요소해석결과와 실험결과의 비교를 통해 접합부의 구조거동을 예측하는데 있어 해석의 타당성을 검증하였다. 면외변형에 의해 유발되는 접합부의 연단거리 조건을 조사하고 최대내력저하정도를 정량적으로 평가하였다. 또한, 변수해석을 통해 얻어진 해석결과의 최대내력과 현행기준식인 AISC, KBC2009, AIJ 및 AISI에 의해 예측된 내력과 비교하여 그 적용성을 검토하였다.
