H形鉄骨を用いたCES内柱梁接合部の終局せん断強度に関する研究

摘要

The objective of this paper is to propose an evaluation method of the ultimate shear strength of CES beam-column joints. FEM analysis for CES beam-column joints was conducted to verify the stress state of concrete in the joint panel, where it was found that the effect of the axial force ratio and the width of the joint panel steel flange on shear strength was small and that the effect of concrete strength on shear strength was dominant. An evaluation method of shear strength was proposed based on analytical and experimental results, and calculated shear strength was in good agreement with the experimental data.%CES合成構造柱梁接合部の部材実験および3次元非線形FEM解析を行うことにより、接合部パネルの内部応力状態について検討を行なった。本研究により得られた知足を以ドに示す。
