Abstract

Abstract

In order to solve the problem of interface void defect of composite steel plate shear wall, based on the hydration heat of concrete itself, infrared thermal imaging method was used to detect the interface void defect of composite steel plate shear wall by using the temperature difference between steel plate and concrete itself. The results showed that: under the condition of concrete hydration heat, the defect location and size of the interface void of composite steel plate shear wall could be effectively identified. When the temperature difference during molding was 15 ℃, the void defect with an area of more than 1 cm² could be identified. When the temperature difference during molding was 10 ℃ or 5 ℃, the void defect with an area of more than 4 cm² could be identified. The method could be more convenient and fast for engineering detection, and could be convenient for real-time tracking detection when pouring concrete. It showed higher practical application value.
