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*中國博士后科學(xué)基金資助項(xiàng)目（20070410174），上海大學(xué)創(chuàng)新基金資助項(xiàng)目（sdcx2012031）。作者簡介：黃興，博士，副教授，Email: hxing01@staff.shu.edu.cn。參考文獻(xiàn)［1］FENG FU, DENNIS LAM, YE JIANQIAO.
