dc.description.abstract이 연구에서는 실험적 연구를 통해 오스테나이트계 스테인리스강(STS304)와 일반구조용 강재인 탄소강(SS275)의 이종간티그 용접접합부의 최대내력과 용착금속 파단메커니즘을 조사하였다. 실험체의 주요변수는 용접길이와 하중방향에 대한 용접방향이다. 실험체의 파단은 용착금속에서 인장파단과 전단파단이 발생하였다. 모재와 용착금속의 재료성질은 한국산업규격(KS)에서 규정하는 최저요구조건을 만족하였다. 하중직각방향 용접선을 갖는 TFW 시리즈 실험체의 내력은 하중방향 용접선을 갖는 LFW 시리즈 실험체의 내력보다 높았다. 현행설계기준식인 미국토목학회(ASCE), 한국설계기준(KDS)과 미국강구조학회(AISC) 기준은 이종강종 용접접합부의 최대내력을 과대평가하거나 과소평가하는 것으로 조사되었다.-
dc.description.abstractThis paper investigated ultimate behaviors such as ultimate strength and weld metal fracture mechanism of austenitic stainless steel (STS304) and carbon steel (SS275) welded connections with TIG (tungsten inert gas) welding through test results. Main variables of specimens are weld length and welding direction against loading. Fractures of specimens were classified into tensile fracture and shear fracture in weld metal. Material properties of base metal and weld metal satisfied the minimum requirement of Korean Standard (KS). Strengths of TFW series specimens with transverse fillet weld got larger than those of LFW series specimens with longitudinal fillet weld. It is known that current design specifications such as ASCE, KDS and AISC did not provide accurate strength prediction for the dissimilar steel welded connections with weld metal fracture.-
