T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 T-type beam-to-column connections in steel reinforced concrete frames subjected to monotonic and alter-nately repeated loading. Sixteen specimens which were designed so as to prevent flexural andshear failure of beam and column elements were tested, whose connection panels were madeof pure steel, pure concrete or steel-and-concrete. The effects of the ratio of beam width tocolumn width on the behavior of connections were investigated. Main discussion wasconcentrated on shear strength, deformability, hypothetical failure mechanism and shapes ofhysteresis curves of connections. The analytical model was formulated to simulate thebehavior of the test specimens and comparisons were made between the calculated andobserved behaviors.
