오스트나이트계 스테인리스강(STS304) 모살용접 접합부의 최대내력

다국어 초록 (Multilingual Abstract)

Generally, stainless steels have excellent corrosion resistance and durability and among them, austenitic stainless steel (STS304) has been utilized widely in building. Until now, many researches on the application of stainless steels as structural steels have been performed thanks to the global need for sustainability in structures for the reduction of green house gas emission. In this paper, ultimate behaviors such as ultimate strength and fracture mechanism of filles welded connections between stainless steel structural members have been investigated through monotonous tensile test results for welded connections. Specimens are fabricated with the number of welding, weld length and welding direction as main variables. In addition, ultimate strengths by test were compared with those predicted by current design standards; ASCE for cold-formed stainless steel structural members and KBC2009 for hot-rolled steel. Therefore, improved approach for estimating the ultimate strength of fillet welded connections is suggested.
