以某既有建筑玻璃幕墻為研究對象，利用激光測振儀獲取大量玻璃面板一階自振頻率，并以此為評價指標，結合理論分析和數值模擬結果，對該既有建筑玻璃幕墻安全服役狀態進行分析評估。提出首先基于概率統計法進行動力特性異常對象篩查，然后對異常對象進行重點考察和安全服役狀態確認的評估方法，并通過實際工程驗證了激光測振技術評估玻璃幕墻安全服役狀態的可靠性和可操作性，體現了激光測振技術非接觸和可遠程測試等優勢。

Taking an existing building glass curtain walls as the research subject, a large number of first?order natural frequencies of glass panels are obtained using a laser vibrometer,which serves as anevaluation index. Combined with theoretical analysis and numerical simulation results, the safety andserviceability status of the existing building glass curtain walls are analyzed and assessed. This paperproposes an evaluation plan that initially screens for abnormal dynamic characteristics of glass panelsbased on statistical probability methods, and then conducts a focused examination and confirmation of theserviceability status for the abnormal objects. The reliability and operability of laser vibrometry technologyhave been verified through the actual engineering projects, demonstrating the advantages of non?contactand remote measurement capabilities of laser vibrometry technology.
