抄録

In order to clarify the seismic resistance of steel moment frames, it is necessary to establish an analytical model of RHS columns that can simulate the members' behaviors including post local buckling and deterioration under bi-directional horizontal forces and axial force. In this study, a multi spring (MS) model which consists of elastic and inelastic elements was employed in the analysis. The hysteretic model of the axial springs which compose the inelastic element was established based on the hysteretic model of RHS columns under uniaxial bending. In addition, a series of cyclic loading tests of RHS columns under random bi-directional horizontal forces and constant axial force were conducted to calibrate the proposed analytical model. The simulated RHS column behaviors, including post local buckling and deterioration, agreed with the experimental results.
