基于应变模态方法的玻璃幕墙开胶损伤识别研究

he approaches to identify the damage in glass curtain wall are discussed by using strain modal in this paper. The glass curtain wall is reduced to a sheet with simply supported edges, by lifting the constraints of the boundary to simulate the damage of silicone sealants. The glass curtain walls in different conditions are simulated to discuss the ability of the strain modal in the damage identification of glass curtain wall. It is show that the damage location and extend can be identified accurately by using the strain modal.
