The capability of steel structures for fireresistance is bad, therefore the study on fireresistance of steel structure has long been put emphasis on in the fields of construction safety.
由于钢结构的耐火性差，其抗火研究一直是建筑安全领域的研究重点。

The fireresistance mechanism lies in three aspects, namely fire resistant tree species, rational construction forest belts and its environment.
防火林带阻火机理有三个层次：防火树种、结构合理的防火林带及其形成的火环境。

Advantageously, the construction element (1) exhibits both optimum self-supporting characteristics and a good fireresistance in case of fire.
