In this study, an experiment is performed to evaluate the shear strength performance of a built-up beam composed of a sinusoidal corrugated web with a depth of 1000 mm or more. In order to compare the effects of automatic welding type, a total of 4 specimens are manufactured by using one-sided automatic welding and two-sided automatic welding. The shear strength performance is verified by comparing it with the value based on the design guidelines of the Korean Society of Steel Construction. It is considered that the corrugated web and flange can achieve sufficient integral behavior effect by single-sided automatic welding. The shear strength of most specimens obtained through static loading tests was found to exceed the values of the design guidelines. Since the fracture pattern appeared near the support point, it is judged that the shear strength will be further improved if the support point is reinforced.
