摘　　要：利用有限元分析软件ABAQUS建立了8个节能砌块隐形密框复合墙体温度场模型,研究了不同受火时间、受火面数与抹面方式对有抹面节能砌块复合墙升温过程中温度场分布的影响规律,以及对整体墙体耐火性能的影响。通过与已有试验对比分析表明,基于ABAQUS的有限元分析结果与试验结果吻合较好,为节能砌块隐形密框复合墙体的耐火性能研究提供一定的参考。By using the finite element analysis software ABAQUS,the temperature field model of 8 energy-saving block and invisible multi-ribbed frame composite walls were established.The influence of different fire time,number of fire surfaces and coating methods on the temperature field distribution of energy-saving block composite walls with coated surfaces during the heating process and the influence on the fire resistance of the whole wall were studied.The results of the finite element analysis based on ABAQUS are in good agreement with the experimental results,which provides a reference for the study of the fire resistance of the energy-saving block and invisible multiribbed frame composite wall.
