In order to clarify the structural behavior of press-formed RHS as columns, the full-scale cyclic laoding tests with six different type of the beam-to-column connections were carried out. Geometric dimensions were □600×t32mm RHS for columns, 1,000×400×25×40mm BH for beams, respectably. In this case, the ratio of the plastic modulus of section between beam and column was 1.46. Steel grade used was SM 490A. Test results obtained are as follows: (1) the joint panels are firstly in yielding condition and account for over 50% of the flame deformation in each case. Also, they have stable and sufficient deformation capacity. (2) The hysteresis curves of the flame, joint panel etc. of each specimen are well-balanced. (3) Brittle fracture does not occur at RHS.
