摘要
对某厂房主要受力构件及网架结构屋盖火灾后主要性能进行了检测及评估.主要对过火区构件进行了火灾后结构烧伤深度、结构强度、裂缝及承载力等方面进行评价,并对厂房网架结构屋盖进行挠度及网架支承高差的检测,从而确定火灾后厂房整体结构的安全性能,提出安全性评估意见.
The detection and evaluation of main performance on the main loaded component and the roof of lattice truss structure of a factory building were carried out. The main aspects of evaluation are depth of burn, structural strength, crack and bearing capacity of the component in burning area. Also the deflexion and differential height are detected, in order to determine its global safety perfornlance and make suggestions on the evaluation of safety.
