The articles are raised about semi-rigidjoint in "Code for Design of Steel Structures" (GB50017-2003) promulgated recently. But it has no necessary theoretical help.
The stiffness matrix of semi-rigid steel frames and the fixed end moment are deduced, based on the connection element method incorporating the effects of joint flexibility.
采用连接单元法，考虑连接柔性的影响，推导出半刚性框架梁柱的刚度矩阵及半刚性梁的固端弯矩。

The finite element model of the semi-rigid connection between members of frame structures is established in this paper, and it is applied to the model of joint parameters identification.
