[提要]  导出了半刚性钢框架结构分析的一般方程，讨论了半刚性简单门式刚架的内力特征，指出了欧洲规范^[4] 刚柔性界定可能导致的内力误差及其存在的不协调性，同时提出了改进刚柔性界定的建议。

The general equations for semi-rigid steel structures are deduced. Some characters about internal forces in semi-rigid frames are brought to light. The possible latent errors and incongruity caused by the definition in Eurocode 3 are pointed out. A suggestion on classification of semi-rigid points is made for the frame.
Keywords:  semi-rigid structures; internal force; frame; steel frame
