确定结构几何变形关系的简便方法

The Simple Method to Confirm the relation between the geometric deformations in a structure

本文对工程结构（无论是静定的还是超静定的结构）的几何变形关系进行分析和讨论，指出了传统几何作图法的繁琐与不足，提出了建立在逆向思维方式和高等数学基础上的解析方法，比之几何法更加简便，易于掌握。

This article analyzes and discusses the relation ship between the geometric deformations in an engineering structure (no matter it is static determinate or static indeterminate.).It points out that the traditional geometric-deformation-drawing method is complicated and has shortcomings.Therefore an analytic method based on the converse thinking manner and higher math is presented.The new method is simpler than the geometric method and is easy mastered.
