Scallops of the beam-web at welded beam-to-column connections of steel frames bring partial loss of cross sections at the part subjected to large bending moments when a severe earthquake occurs. Therefore, they are not desirable from the point of view of mechanical behavior. This paper presents the bending tests performed using specimens of beam-to-column joints on shop assembling carried out to investigate the effect of non-scallop methods and beam-scallops on fracture behavior, ultimate strength and deformation capacity of the steel beam-ends. It is concluded that a beam without scallops has earlier brittle fracture and higher strength, and larger deformation capacity than a conventional beam with scallops. Finally, it recommends the details of the end of the beam of the non- scallop method of construction with the cost performance being based from the view point of the design, the building.
