摘　　要：通过对齿槽式、外贴钢板齿槽式和无齿直缝植弯起钢筋式三种柱后接梁接头形式的9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水平。讨论了各种接头形式的抗剪性能和机理,由此建立了它们的抗剪承载力验算方法,且所提建议公式与试验结果吻合较好,可供工程设计参考。A total of 9 tests were conducted on three kinds of full scale beam-column connections, including tooth-grooved connection, sticking steel plate welded angle iron connection and roughened interface with inserting bent-up bars connection. It was confirmed that the roughened interface connections had better performance, its strength was up to the strength of integral casting beams. It was also discussed the shear behavior and mechanism of the three kinds of connections. The formulas to calculate the shear capacity of connections Were proposed, it is shown that the theoretical values were in good agreement with those of the test, and they could be used as reference in engineering practice.
