Abstract

Abstract

After determining the thermal parameters, the boundary conditions of the fired surface, the backfire surface, and the contact conditions, the temperature field analysis model of the prefabricated box-plate composite wall was constructed by the FEM software ABAQUS. And the validity of the model was verified by relevant test results. On the basis, the temperature fields of the composite wall as well as its key measurement points were obtained, and the parameters of each component were also be analyzed. The results showed that the thickness of rock wool, the type and the thickness of cladding sheet, the numbers of layers had obvious influence on the temperature fields inside the composite wall, and the others factors had little effect. According to the analysis results, the fire-resistant design idea of composite walls and the temperature prediction formula of key temperature control points were proposed.
- prefabricated box-plate composite wall,
