[摘要] 通過對齒槽式和無齒直縫植彎起鋼筋式兩種柱后接梁接頭形式的6個足尺試件的試驗研究，證實無齒直縫植彎起鋼筋式接頭具有較好的抗剪能力，其承載力可以達到整澆梁的水平。對比分析了兩種形式接頭的抗剪性能和機理，給出了一些設(shè)計建議，可供加固設(shè)計參考。

( Scbool of Civil Engineering, Harbin Institute of Technology, Harbin 150090, China )Abstract: A total of 6 tests were conducted on two kinds of full scale beanrcolumn 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 engjneering practice
