초록
The purpose of this study is to investigate the ultimate strength of carbon steel (SS400) fillet-welded connections with weld metal fracture not base metal fracture through monotonic tensile test. Main variables of the specimens are weld length and welding direction against applied force. Three types of specimens with transverse fillet weld against loading direction (CTFW series), longitudinal fillet weld against loading direction (CLFW series) and full fillet weld (CFW series) failed by tensile fracture, shear fracture and block shear fracture in the weld metal, respectively. Test strengths were compared with design strengths calculated by current design specifications (Korean Design Standard [KDS] and American Society of Steel and Construction [AISC]) and the design codes tended to underestimate the weld metal fracture strength of test results by up to 73 %.
