首先建立一種剛架無軸向變形之分析法。藉由將人們分析的思考方式加以整理，而演變成具有系統化之方法，稱之為梁鏈法( beam-chain method )。針對結構在桿件數量及幾何因素之變化，建立對應的法則( rules )來處理。然後用一般含有軸向變形之分析法計算，比較差異之大小，藉以瞭解並確認無軸向變形因素對該種結構型態的影嚮。並得到簡易的判斷法則。 A method of the analysis of frame, under the assumption of neglecting axial deformation, is developed. It is made through deducing, odifying the imaginary model of human being. So we get a analytical system called "beam-chain" method. For each kind of beam-chain, a corresponding rule in the knowledge base is established. The rule deal with the characteristics of material property and geometrical factors.
Two methods are compared on the factor of axial deformation. So, we can comprehend which type of the structures make much difference on this factor. From these results we induce some simple rules for the application on stress analysis.
