摘　　要：介绍了一种大型结构分析的新的数值方法超级有限元法。利用该方法可大大降低结构分析的计算工作量。本文推导了高耸桁架结构的超级元列式，可用于塔架等大型桁架结构的力学分析。算例说明这是一种实用的大型复杂结构分析的数值方法。A new numerical method, i.e., the super finite element method is given of analyzing a large scale structure. Applying this method can decrease the amount of calculating task about structure analyses greatly. The paper has inferred the super element determinants for towering truss structures, which can be used in mechanical analysis of the large scale towering truss structures, such as tower truss, and soon. The calculation examples show this is the numerical method which is very practical in analyses of the large scale and complicated structure .
