Steel frame with welding joint easily occur brittle collapse because of having a low ductility at joints then ， a semi - rigid connected steel frame has large the energy absorption capacity which can resist dynamic loads and the using steel qualities of bracing system and joints are small so adopting a semi - rigid jointed steel frame is economical and stable but for semi - rigid connections are complex and variable ， in conventional analysis and design of steel structures ， it is usually assumed that the connections between columns and beams are either rigid or pinned the analysis of steel frames adopting the assumption can simplify the procedure of analysis and design ， but cannot precisely reflect structural practical circumstance and the errors of calculating results are large ， even ， get incorrect conclusions semi - rigid connection was referred to in chinese code for design of steel structures ( 2001 ， 10 ) ， however ， it isn ’ t specified how to apply semi - rigid joints in design in fact it cannot be carry out the purpose of the paper give a calculating method that accords practical engineering and easily put into effect worthwhile it is going to promote the development of semi - rigid jointed steel frame in design and heighten structural stability in the paper ， at first some commonly employed methods for the modeling of connection behavior are introduced richard abbott function modeling of connection is adopted for extended end plate bolted connection by the 34 test data comparing to regression analysis indicate richard - abbott function modeling of connection represents an excellent fit to test data then after a semi - rigid joint behavior can be modeled as a finite stiffness rotation spring ， base on rotation and displacement equation derive the element stiffness matrixes with semi - rigid connections where the effects ofj ointed flexibility geometric non - linearity and shear forces in the connection deformations have been considered in and fixed - end forces are modified finally , a program for calculating semi - rigid with incremental - iterative method has been 本文的目的就是为半刚性连接钢框架的设计提供一种既符合工程实际又简便易行的计算方法，供规范使用过程的补充、延伸或参考；同时，也将促进半刚性连接钢框架设计技术的发展，为提高结构安全性能、节省工程成本发挥应有的作用。本文首先介绍了常见的几种应用较为广泛的梁柱连接弯矩转角关系模型，在分析比较的基础上，选用richard ? abbott函数模型作为外伸端板连接弯矩转角关系模型，通过对34个外伸端板连接的实验数据与回归分析得到的参数比较可知，经回归分析得到的此模型参数与实验数据符合较好。然后用弹簧表征连接点的转动刚度，根据梁的转角位移方程推导出半刚性连接的刚度矩阵，在单元刚度矩阵中考虑了节点柔性、几何非线性和剪切变形的影响，并对固端力进行了修正，最后用增量迭代法编制有限元程序进行计算和分析。
