Presented in this paper is an experimental research to clarify what kind of reinforcement is more effective for beam-to-column connections consist of square-tube columns and rectangular-tube beams. So, we are concerned with the behavior of four different types of connections. Those specimens are loaded to be subjected to unti-symmetrical bending, shear and thrust in their connections. In consequence of experimental research, the connections which have diaphragms penetrating to tube-column or have stiffeners alongside with beam-web similar to horizontal hunch are excellent on strength and stiffness. Further, on the theoretical study, we discuss the shearing stress distribution of square-tube the wall thickness of which is more and more thin. Making use of the solution in the Part I, we can obtain the limiting values of thin wall. And the values of this approximate solution are in accordance with the values of shear flow theory and experimental values.
