既有建筑局部火灾后的损伤鉴定与加固处理
Damage Assessment and Strengthening Scheme for an Existing RC Structure After Fire Hazard
【摘要】 火灾造成的建筑物损伤直接影响其使用安全,因此火灾后建筑物的损伤鉴定具有重要意义。结合某具体工程案例,对受火灾影响范围内的结构损伤状况、损伤层厚度、材料力学性能等进行检测,对混凝土结构的火灾损伤特征进行分析,提出了一些新的损伤鉴定思路,并针对构件不同损伤状况提出相应的加固处理方案。
【Abstract】 Existing structures may be caught fire,and damages due to fire hazard can influence the safety of the structure directly.Damage assessment of fired structures is very important.Because of complexity and uncertainty of structural damages,to some extent it is still difficult to assess damages of fired structures.According to procedures,contents and methods for damage assessment of fired structures,damaged condition,thickness of damage layer and mechanical properties of materials of an actual fired RC structure were tested,and some damage features of fired RC structure are analyzed.Some new ideas of damage assessment are suggested.Finally,different strengthening and repairing scheme are put forward for different damage degree.
