摘要
主要介绍了高层钢结构建筑的火灾影响分析 ,通过数据 ,从理论上阐述了钢材在高温下强度退化 ,以及在火灾下钢结构温升快的特性 ,从而反映出钢结构在高温下裸露部分耐火差的本质 ,并结合相应特性 ,提出对钢结构建筑防火材料的要求。
The fire features and affecting factors are mainly introduced of high-rise building's steel structure. The data and theoretical analysis show that high temperature causes the loss of steel's strength and rapid increase of temperature of steel structures, indicating that the exposed portion of steel structures is poorly fire-resistant. Proposals are given concerning the requirements of steel structure fire-resistant materials.
