摘　　要：通过对齿槽式和无齿直缝植弯起钢筋式两种柱后接梁接头形式的6个足尺试件的试验研究,证实无齿直缝植弯起钢筋式接头具有较好的抗剪能力,其承载力可以达到整浇梁的水平。对比分析了两种形式接头的抗剪性能和机理,给出了一些设计建议,可供加固设计参考。A total of 6 tests were conducted on two kinds of full scale beam-column connections, including tooth-grooved connection and roughened interface with inserting bent-up bars connection. It is confirmed that the roughened interface connections have better performance, its strength can come up to the strength of integral casting beams. The shear behavior and mechanism of the two kinds of connections are compared, some design suggestions are given, and they can be used as reference in engineering practice.
