擷取有關幾何因素影響結構穩定的知識，以建立一個知識庫。一般穩定元素用桿件互相連結，在複雜桁架中常用由五支桿件組成的，而功能類似於一支桿件之複桿來連接。本文探討複桿之性質及其對穩定之影響外，尚有除桿法可簡化原來桁架，以作穩定判斷。將新的知識及舊有相關知識組成更完整知識庫，擴大應用功能。 To acquire the knowledge about geometrical stability of the structures. So we can build a knowledge base. Stable elements are connected by three bars or equivalent bars between them usually. In complex truss , stable elements are connected by a so called complex menber and two single member. A complex member consists five single members , but its action is similar to a single member. This paper describes the properties of complex member and effect of the complex member on geometrical stability. The knowledge is obtained by this process. In addition to the knowledge about complex member , there are some other rules about geometrical stability are obtained also. So we build a more completely knowledge base by adding these new rules to the old knowledge.
