现代化城市中,大型商厦及高层建筑鳞茨节比,一但遭遇火灾后迅速进行修复或是重建,以尽快恢复其使用功能,是挽回和减少灾害损失的唯一途径。 对遭受火灾损伤的混凝土建筑物,由于钢筋混凝土的耐火性,一般不容易烧垮崩塌,因此如何正确评估火灾伤害程度,并据以进行修补、加固、或是拆除重建,就显得更为迫切。 国外对建筑物火灾损害的评估研究,发展较快且较为深入,我国近年来各地建筑科研单位也做了初步的研究。 In modern cities, large commercial buildings and high-rise buildings in the city are the only way to restore and reduce disaster losses if they are repaired or rebuilt quickly after a fire. Concrete buildings that are damaged by fire are generally not easily burned and collapsed due to the fire resistance of reinforced concrete. Therefore, how to properly assess the degree of fire damage and repair, reinforce, or dismantle and rebuild them becomes even more urgent. The assessment and study of fire damage to buildings abroad has developed rapidly and in depth. In recent years, China’s construction and scientific research units have also made preliminary research.
