L字形骨組で構成される鉄骨鉄筋コンクリート柱はり接合部のせん断破壊に関する実験的研究

Abstract

The main objective of this investigation was to study the shear behavior of rigid moment-resisting connections in L-shaped SRC frames subjected to monotonic and well-defined alternatelyrepeated loading to deflection larger than the yield deflection. 16 specimens which were designedso as to prevent the flexural and shear failure of structural beam and column element were testedwith a variety of the ratio of beam width to column width, involving steel panel alone, concretepanel alone and steel-concrete panel. Main discussion was concentrated on the shear strength, deformability, hypothetical failure mechanism and shapes of hysteresis curves of connections.The analytical model was formulated to simulate the behavior of the test specimens and comparisonswere made between the calculated and observed behavior.
