Abstract

In order to evaluate compressive strength of centrally-loaded steel column at elevated temperature, new FE analysis techniques and assumptions of model were applied in this study. It also includes comparison with the existing studies, and a new design equation for centrally-loaded steel column at elevated temperature was proposed. The proposed equation was the most accurate of the three design equations(EC3, AISC, proposed equation) when comparing with the coefficient of determination on the simulated results and test results.

중심축 하중을 받는 고온상태 강재기둥의 압축강도를 해석하기 위하여 새로운 유한요소 해석모델을 제시하였으며, 기존 연구를 대상으로 해석가정 및 유한요소해석 기법을 비교 분석하였다. 또한 유한요소 해석결과를 바탕으로 새로운 고온상태 강재 기둥의 설계식을 제안하였으며, 해석결과 및 실험연구 결과와 비교하였을 때 AISC와 EC3 설계식보다 본 연구의 제안식이 고온상태 강재기둥의 압축강도를 정확하게 표현하는 것을 확인하였다.
