空间网架结构构件的损伤检测及鉴定

Damage Detection and Identification of Structural Components of Space Grids

文中以某综合大楼网架结构为背景,进行了网架结构杆件变形检测,并结合现场网架结构构件损伤检测结果及有限元模型验算分析结果,进行了承载能力鉴定评级,对类似问题的解决提出参考意见,可为后续同类工程的检测鉴定提供借鉴。

Taking the grid structure of a complex building as the background,the deformation detection of the truss structure members was carried out,and the bearing capacity identification and rating was carried out based on the damage detection results of the on-site grid structure members and the finite element model verification analysis results.Finally,several points for attention were put forward for similar problems,providing reference for the subsequent detection and identification of similar projects.
