繰返し荷重を受ける鉄骨コンクリート柱はり接合部の弾塑性性状に関する実験的研究

Abstract

To investiagate the elasto-plastic characteristics of the beam-to-columm connection of a steelconcrete structure, twelve specimens were tested with a variety of the cross section under repeatedand monotonous loading. The test specimens used in this experiment were beam-type and theloading apparatus was designed to realize the state of stress in the actual connection panel. Theirstrength, stiffness, energy absorption and damping were discussed. Test results indicate that theconcrete portion in the connection panel contributes considerably to the shear capacity as long asthe shearing strain of connection panel is less than one per-cent under repeated loading.
