工业企业中大空间建筑是近年来我国大量使用的建筑形式,对其进行耐火性能研究已成为当前钢结构耐火研究领域的热点问题。基于此,本文综述了当前工业企业中大空间建筑室内温度场研究成果,介绍了大空间钢网架结构所用钢材高温材料模型的试验研究,说明了钢结构构件的耐火试验进展和数值模拟的相关进展,详细阐述了基于结构整体的耐火性能研究现状,并对大空间钢网架结构耐火研究趋势进行了展望。

Large space building in industry has taken more and more important roles in recent years in our country. The study of its fire resistance behavior has become a hot issue in the current large space grid steel structure field. Based on this, this paper reviews the current research of indoor temperature field in large space building, and introduces the experimental study of large space steel grid structure using steel high temperature material model. It shows the progress of steel structure fire resistance test progress and numerical simulation, describes in detail the status of refractory properties based on the whole structure, and the prospect of large space steel grid structure of refractory research trend.
