  • ANALYTICAL MODEL OF RHS COLUMNS UNDER RANDOM BI-DIRECTIONAL HORIZONTAL FORCES  [in Japanese]

    ISHIDA Takanori , YAMADA Satoshi , SHIMADA Yuko

    … 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. …
