摘　　要：众所周知,结构力学中一般采用零载法开展复杂平面体系几何组成分析。然而,零载法需进行较多的计算,分析过程仍显繁琐。为了简化复杂平面体系的几何组成分析,本文将杆件替代法与零载法结合起来,建立了复杂平面体系几何组成分析的基本规则。最后,通过算例分析论证了本文方法的可行性与优越性。It is well known that the zero-load method is generally used to analyze the geometric construction of complex plane systems in structural mechanics. However, the zero-load method needs involved calculation,and the analysis process is cumbersome. In order to simplify the analysis of geometric construction of complex plane system, based on the substitute member method and the zero-load method, a new method for geometric construction analysis of complex plane systems is developed, and the basic rule of geometric construction analysis of complex plane system is presented. Finally, the feasibility and superiority of this method are demonstrated by several examples.
