中文摘要：本文提出了利用应变测量数据检测隐框玻璃幕墙结构胶损伤的方法,首先测量出幕墙玻璃板在外部激励下振动时各测点的动应变数据,然后综合比较各测点应变数据的变化情况,结构胶损伤的部位处必然对应着相对更大的应变数值,据此便可对结构胶是否损伤和损伤的位置作出准确判断。对一个1m×1m的玻璃板进行了结构胶损伤检测实验,结果表明了所提方法是合理可行的。

外文摘要：In this paper, a damage detection method using test data of strain is proposed for detecting the damage of structural silicon sealent used in hidden frame supported glass curtain wall. Firstly, the dynamic strain data of all test points on the glass plate under the vibration caused by external incentives are measured, and then the change of strain data of each test point comprehensively are compared. In the end, damaged locations of structural silicon sealent can be detected by the relatively greater values in the measured strains. A structural silicon sealent damage detection experiment on a glass plate （lmxlm） is used to validate the proposed method. The results show that the proposed method is effective to assess the damage of structural silicon sealent.
