| 中文摘要: |
| 伪可变体系是介于常可变与不变体系间的一种结构，通常其识别较为复杂。本文基于计算机分析方法，讨论了伪可变复杂系统的两种判别程序。首先给出仅有一个自内力模态下，简单情形的识别过程。然后分析迭代判别法在判定伪可变复杂系统中的应用。最后提出多阶段自内力模态识别法，结果表明这一方法通常要比迭代法简便得多。本研究结果有助于对现代预应力结构体系的研究． |

| This paper discusses some identifing methods for complicated quasi-variable systems.Asimple case which has only one self-internal-force mode,can be easily identified by usingcomputer procedure,Then we introduce iterative method to identify a complicated systembased on product-force. Finally,a self-internal-force mode method,which is divided threesteps, is proposed to analyse a more complicated system,The method results are more sim-ple than iterative method.So far,for any structural system,its geometrical constructionproperties can be identified by the results of this paper,The study results are useful to re-serch modern prestressed structure systems. |
