空间框架建筑结构静力分析的超级元法解

THE STATIC ANALYSIS OF SPACIAL FRAMES IN ARCHITECTURAL STRUCTURES BY THE USE OF SUPER-ELEMENT METHOD

本文发展一种建筑结构简化计算的新方法。这种方法的整体结构数值分析按其连续化分单元(超级元)进行,但单个构件又按常规有限元计算,故应用于复杂的空间框架结构提供了一种自由度及工作量极少又适用性强的高效实用分析方法,可望在微机上实现。

In this paper, a newly developed simplified method for the computation of architectural structures is given. In this method, the analysis of the whole structure is done by the use of the supper-elements which discritize continuously, yet for the analysis of single members it is performed with the conventional FEM. Thus, when this method is applied to complicated spacial frame structures, it furnishes a very practical and effective method with few degrees of freedom, much less computational work and wide applicability. Also, it may be used on microcomputers.
