This paper presents the structural performance of H-beam-and-RHS column subassemblage without any diaphragms. The column thickness at beam-to-column connection area is increased by the induction heating procedure. To discuss the reinforcing effects by the horizontal haunch of beam and column with increased thickness, the cyclic reversal loading test for beam-and-column subassemblages was carried out. To represent the reinforcing effect of column with increasing thickness, constant axial load was applied on the top of the column. The elastic-plastic behaviors of subassemblages are evaluated by using finite element and numerical in-plane analyses. The full plastic and ultimate strengths of the beam-to-column connection are estimated by the yield line theory.
