随着我国经济建设的发展，大型建筑如展览馆、候机楼、大型市场、高级宾馆及工业厂房等不断增多，采用钢结构的建筑也随之不断增加。由于钢材自身在常温下优异的物理力学特性及不燃烧性，因此钢结构的防火隔热保护问题曾一度被人们所忽视。但是，国内外长期的试验和研究结果表?
With the development of economic construction in our country, the number of large buildings such as exhibition halls, terminal buildings, large markets, high-class hotels and industrial plants has been on the rise, and the number of buildings with steel structures has also been on the rise. Due to the excellent physical and mechanical properties and non-combustibility of the steel itself at normal temperature, the fire protection and heat insulation of steel structure was once neglected by people. However, domestic and foreign long-term test and research results table?
