摘　　要：本文通过三榀转换梁的试验研究，对高层建筑转换梁结构的截面选择、配筋设计以及钢筋端部锚固构造要求等进行了分析。研究表明，满跨转换梁与上部墙体有共同作用，转换梁抗弯抗剪承载力以及墙板的抗剪承载力均有相当的安全度，最终破坏发生在墙体底部局部压坏。不满跨转换梁的试验结果表明，无墙体部位转换梁的抗剪决定着整个转换结构的承载能力，上部有墙体部位墙梁有共同作用，应按有限元法计算内力，并进行配筋设计。Based on the experimental research of three transfer beam models, this paper analyses the determination of sections, reinforcing methods and anchoring of bars at the beam end of transfer beams in highrise buildings. The experimental results of full span wall on transfer beam show that there is interaction between the beam and the shear walls above. The flexural capacity of beam and shear capacity of both beam and the wall above is quite sufficent while the ultimate destruction arises from local pressure failure at the bottom of shear wall near the column. The experimental results and analytical results by finite element method of partial span wall on transfer beam show that the shear capacity of the partial transfer beam without shear wall above determines the loading capacity of whole transfer structure, and there is joint action between structural wall on the transfer beam and the beam itself, which should be designed with the finite element method.
