摘　　要：本文针对复杂杆系结构提出一种超级有限条的分析方法。这种方法基于半连续半离散思想将各杆件结点自由度归结为整体结构自由度；进一步又将整体自由度简化为少数结线自由度上机计算。这将为复杂结构体系开拓一条简便、实用的工程分析途径。A super finite strip method for complex rod-systems has doveloped in this paper. By means of semi-continuity and semi-discretization idea, this method expresses the dots of each node of the rods bythe global dots of the structure. Furthermore, the global dots are reduced to much fewer ones of nodallines of the strips. It will lead to a simple and practicable way for the analysis of complex structures.
