The results show that the calculating data can agree preferably with experimental data. Therefore, the computing formulas can be used to decide the rigid behavior and study parameters of the semi-rigid composite edge joint for the semi-rigid composite edge joint for beam-column end-plate connection.Keywords: extending concrete flange; anchorage; beam-column end-plate connection; semi-rigid composite edge joint; moment capacity*中国博士后科学基金资助项目（20070410174），上海大学创新基金资助项目（sdcx2012031）。作者简介：黄兴，博士，副教授，Email: hxing01@staff.shu.edu.cn。参考文献［1］FENG FU, DENNIS LAM, YE JIANQIAO.
