This paper proposes design procedures that yielding of beams occurs before RHS-column to beam connections stiffened by exterior diaphragms yield. Cyclic loading tests of beam-column subassemblages for interior columns were conducted in order to verify the validity of the proposed design method, and elasto-plastic behaviors of beam-column subassemblages for exterior column or concrete filled tube column were investigated. The test results reveal that the design method is valid. Stiffness of beams with exterior diaphragms can be properly predicted by assuming that beams are connected rigidly to columns. Deformation capacities of specimens whose beams are connected to exterior diaphragms with high-strength bolts are substantially larger than that of the specimen that beam flanges and exterior diaphragms are welded.
