This paper addresses the derivation of collapse load of rectangular hollow sections (RHS)-column to beam connections with exterior diaphragm based on the method of plastic analysis. The presented formulae are available for arbitrary shapes of exterior diaphragms, and include the influence of weld details between the diaphragms and the column. In order to verify the validity of the collapse load, tests of the connections were performed. Major findings from the tests are summarized as follows: (1) the yield strength obtained from the tests was about 70 to 80% of the collapse loads, (2) there were 14 to 45% differences between the experimental maximum strength and the calculated maximum strength, (3) the experimental maximum strength of specimens which were expected to fracture in the fillet weld between RHS-column and exterior diaphragm agreed well with the calculated maximum strength, and (4) the assumed collapse mechanisms agreed well with the ultimate states of the connections.
