结果表明：随着弯矩的增加，弯矩-转角曲线由线性特征转变为非线性特征，连接刚 度逐渐降低；端板厚度和梁腹板高厚比对连接的初始刚度及抗弯承载力均有显著的影响。

The thickness of the endplate and the ratio of the height to thickness of the beam web were adjusted respectively to analyze their influence on the moment-rotation curve.The results show that with the increase of the bending moment, characteristics of the moment-rotation curve turn from linear into nonlinear and the stiffness of the connections reduce gradually; the thickness of the end-plate and the ratio of the height to thickness of beam web have a significant impact on the initial stiffness and bending capacity of connections.
