摘　　要：介绍了半刚性梁柱节点的特性和Frye Morris模型,列出了考虑P-△效应的半刚性连接构件的单元刚度,将遗传算法应用于钢框架的优化设计中.编制了程序GASEF,进行了算例计算,得到了一些有价值的结论.<Abstrcat> The authors introduced the character of semi-rigid beam-to-column connections and the Frye-Morris modeling. The element rigid matrix is listed for the semi-rigid connective component, the p-△ effect is also accounted. A genetic algorithm is used for the design of the steel frames.A computing program GASEF is developed and tested by the example. A few valuable conclusions are obtained.
