为开展预应力结构抗火性能分析及火灾后损伤评估提供了基础性素材。
All can be served as basic data for analysis of fire resistance and after-fire damage evaluation of prestressed structures.
因钢管外露，钢管混凝土柱的抗火性能与设计是其在工程实践中的关键问题之一。
The fire resistance behaviour and design of CFST columns are one of the key issues in practice due to the steel tube being exposed to air.
然而，高强混凝土与普通混凝土相比，结构密实，脆性更大，渗透性低，抗火性能差。
However, comparing with the common concrete, the strict construction, the greater crisp character and the lower penetrability, lower firefighting properties.
但钢结构建筑最大的缺陷在于其抗火性能差，因而一种科学、经济、可靠的钢结构抗火设计方法的提出与应用成为钢结构住宅推广与应用的必然前提。
So the advance and apply of a kind of scientific, economical and reliable fire resistance design method became the biggest precondition for the apply of the steel structure domicile.
中空夹层钢管混凝土在传统钢管混凝土基础上改进，使得钢管混凝土的抗弯刚度大，自重轻，耐火性能更好。
Concrete-filled double skin steel tube columns, which have more bending rigidity and fire resistance, but have less weight, are an amelioration of traditional concrete-filled steel tube colums.
