摘要:

介绍了CATAS系统的试验与分析一致性评估技术。通过建立试验结果与计算结果之间的线性回归关系,提出了一致性模糊综合评估方法。在保证一定试验可靠度的前提下,结合区域对比曲线,该方法可以指导修改计算模型。通过对Y7-200A的位移测量和计算结果,验证了该方法的有效性。

Abstract:

The technique for the consistency evaluation of the structural test and analysis is presented. It is one of the key techniques in CATAS system. The relationship between test and analysis data is built by linear regression, and a fuzzy evaluation method is proposed. In case of the high reliability of test, the analysis model can be modified by the guiding of this method. The Y7 200A displacement results are used to demonstrate the technique.

Key words: consistency evaluation, structural test, structural analysis
