摘　　要：回顾了国内外后浇混凝土梁端抗剪问题的研究进展。首先归纳总结了后浇混凝土梁端的抗剪力组成,然后介绍了国内外学者在20世纪和近几年对后浇混凝土梁端抗剪问题的研究情况,还介绍了美国规范ACI318-08,美国PCI手册,欧洲规范PrEN-1992-1-1,加拿大规范CSA A23.3和我国规范CP-PCC-2003和CECS43:92中关于预制梁端抗剪设计的规定,重点讨论了其抗剪机理和计算方法。最后在比较分析的基础上对不同研究成果进行评述,并指出了进一步研究的方向。This paper presents the developments of research on shear capacity of connections of post-casted concrete beams. First, it was summarized that the shear capacity of connections of post-casted concrete beams is consisted of several forces. Second, the research activities of both foreign and domestic scholars in the 20th century were introduced, which was mainly focused on the mechanic characteristics and the methods of shear calculation. Then, to make a comparison, the recommendations on shear capacity of connections of precast concrete beams in codes of ACI318-08, PCI handbook, PrEN-1992-1-1, CSA. A23.3, CPPCC-2003, CECS43 ： 92 were presented. At last, based on comparison and analysis, the current situation of the research on shear ca- pacity of connections of post-casted concrete beams was discussed and the prospect of the problem was proposed.
