摘　　要：在确定箱板装配式组合墙各组成部分的热工参数、受火面和背火面的边界条件、接触条件等关键问题后,采用有限元分析软件ABAQUS建立其温度场分析模型,并用相关试验分析结果验证分析模型的有效性,得到了火灾下组合墙及其关键测点的全过程温度场分布规律,并对各组成部分进行参数分析。结果表明:岩棉厚度、覆面板材的种类、层数和厚度对组合墙内部温度场分布影响较大,其他因素影响较小。最后根据分析结果提出组合墙的抗火设计思路和关键温度控制点的温度预测式。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.
