Grey Correlation Analysis of the Bending Resistance of Lightweight Thermal Insulation Composite Wall

摘要

The research of light thermal insulation composite wall has great significance to the study of alleviating the energy shortage situation and promoting the sustainable development of China. In this paper, the gray correlation analysis was carried out to determine the indicators that influence the bending resistance, including the thickness of the light steel keel, the thickness of the fiber cement plate and the foaming ratio of the concrete. The results of the gray correlation analysis are consistent with the test results of the wall, which indicates that the method of grey correlation analysis can be used to analyze the bending resistance of thermal insulation composite wall, which has a strong practicality.
