摘要
介绍了网架结构在使用过程中出现异常变形后的现场检测内容,分析思路和鉴定评价的工作程序,以及每项工作的重要性。并以一个筒仓网架结构出现部分杆件异常弯曲后,对其进行检测鉴定的工作为例,详细阐述了整个检测鉴定工作中的每个环节。
The paper introduces the detection content about the abnormal deformation of a grid structure in its working course, the analytical thinking and the evaluation procedure. The detecting and evaluation work content of one silo grid structure after abnormal bending of some bars is taken as an example, the whole detecting details and identification were elaborated.
