Structural behaviors of beam-to-column connections has scarcely been studied when the corner weld of box-column section is partial penetration weld. In this study, connection assemblage tests have been carried out with variables of throat thickness of corner weld, plate thickness of inner diaphragm, and, layout and size of beam flange. And the conclusions attained are as followings. 1) Maximum shear strength of corner weld at connection panel increases with throat thickness of corner weld and plate thickness of inner diaphragm, and it depends on the layout of beam flange to corner weld. 2) Yield, general yield and maximum strengths of corner weld at connection panel can be estimated by Eq. (5), (8) and (9), respectively. 3) General yield and maximum strengths of beam end joint can be estimated by Eq. (15) and (16), respectively when wide flange beam is welded to box column. And they are almost independent of the throat thickness of corner weld.
