This paper proposes design formulae for RHS-column to beam connections with exterior diaphragms. In Ref. 7), full plastic strength and ultimate strength were obtained by applying plastic analysis to the collapse mechanism, which consists of yield lines on the column tube wall and three yield zones of the exterior diaphragm under uniform strain condition. In this paper, yield strength and ultimate strength are derived based on some informations obtained by plastic analysis. Next, approximate formulae for evaluating the yield strength and the ultimate strength of the connections are proposed in order to make the method proposed above more practical. Finally, the design method of fillet welded connections between the column tube wall and the exterior diaphragms is proposed, too.
