摘　　要：某电石炉厂房及配料站由于遭受火灾,导致结构出现较大损伤,为了消除火灾事故后结构的安全隐患,需要对厂房进行全面的火灾后结构安全性检测鉴定和加固。现场调查分析了火灾后结构的受损情况,并对构件表面的过火温度进行了推定。在受损构件混凝土强度检测、钢筋力学性能检测、构件变形检测的基础上,考虑构件材料强度的折减,对受损结构的承载能力进行了验算校核,最终对该厂房及配料站火灾后结构的安全等级进行了评定,并探讨了加固修复的方案。The calcium carbide furnace plant and grading station are suffered greater damage because of subjected to fire disaster.In order to eliminate the hidden danger of the structure,the safety detection and evaluation of structure are conducted.The damage of structure after fire is investigated and analysis,and the excessive temperature of the component surface is presumed.The properties of concrete and steel after fire are tested.Based on the results,and considering component material strength reduction,the bearing capacity of structure is calculated.At last,the rating level is assessed and the strengthening scheme of the structures after fire is discussed.
