Study on Stress Influencing Factors Based on Grey Correlation Analysis
摘要
Abstract
Influencing factors on magnitude of concrete stress during the construction course of PC bridge is introduced. Correlation sequences of the stress influencing factor and operators calculation method were formulated comprehensively through the presentation of grey correlation analysis, also, the theory and technique to create stress absolute associated metrix, stress relative associated metrix and stress comprehensive associated metrix were explained distinctly. Factors ' contribution quantity on stress was ascertained through grey correlation analysis, which should be prevented overrun of stresses in order to avoid crack or crush of concrete. Validity of grey correlation analysis was confirmed during stress change trend analyses of one rigid frame bridge construction process,and it is a significant method to keep critical section stress under the acceptable level which keep critical section safe.关键词
