摘　　要：根据四个钢筋混凝土方柱—薄壁柱局部转换节点在竖向荷载作用下的试验研究结果 ,分析了节点中转换梁与其上的一字形薄壁柱的相互作用 ,其中重点探讨了转换梁加腋高度对薄壁柱承载能力的影响。On the basis of experimental results on four specimens of vertically loaded RC joints of local transfer from square column to straight wall, interaction between the transfer beam and the straight wall above it is analyzed. In the test, the effect of height of armpit on the transfer beam upon the behavior of the joint is specially studied. As a result, determination of the design shear force and shear capacity of the transfer beam and calculation of capacity of the straight wall are suggested, taking into account the effect of shear span ratio of the beam.
