  • 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. … 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. …

  • LOADING TESTS OF BEAM-COLUMN SUBASSEMBLAGES HAVING EXTERIOR DIAPHRAGMS COMPOSED OF TWO STEEL PLATES  [in Japanese]

    MATSUO Shintaro , SABURI Kazuhiro , TANAKA Tsuyoshi , INOUE Kazuo

    … 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. …

  • STRENGTH CALCULATION OF RHS-COLUMN TO BEAM CONNECTIONS WITH EXTERIOR DIAPHRAGMS FOR EXTERIOR COLUMNS

    MATSUO Shintaro , TANAKA Tsuyoshi , INOUE Kazuo

    … In this paper, design formulae of RHS-column to beam connections with exterior diaphragms are proposed for exterior columns, where design formulae mean yield strength and ultimate strength. … For the perpose of comfirming the validity of the formulae, we performed monotonic tensile loading tests for beam-to-column connections. …
