In the design of modern building facades, glass curtain walls are becoming increasingly prevalent, primarily due to their energy efficiency and environmental frieess, as well as their immense value in enhancing architectural aesthetics; they have long been a mainstream choice for exterior facades both domestically and internationally. However, over time, these building envelope structureably exhibit various practical safety issues due to material aging, construction defects, and prolonged exposure to complex climatic conditions. The safety hazards associated with glass curtain wall structures include the aginracking, and failure of structural adhesives, degradation of sealing performance leading to leakage, and more perilous sudden incidents such as tempered glass cracking and spontaneous explosion, as well as looslling panels. As buildings age, these safety hazards can no longer be ignored. Consequently, the need for systematic safety inspections of existing building curtain walls has become particularly urgent in various regns. Taking Zhejiang Province as an example, relevant regulations issued by local management authorities explicitly require that when curtain walls exhibit panel deformation, loose or cracked connection components, or when the curtain wall exceed their design service life but must continue to be used, the owners of the relevant buildings must regularly commission qualified inspection and appraisal agencies to conduct safety appraisals. Scd reasonable inspection technologies serve not only as a means to identify risks but also provide a basis for subsequent maintenance decisions, thereby extending the actual service life of curtain walls.
