摘 要: 基于应变模态方法,对单元式玻璃幕墙的损伤识别进行研究。将单元式玻璃幕墙简化为四边简支的薄板,通过改变边界约束模拟玻璃幕墙的边界开胶损伤。通过对某玻璃幕墙在不同工况下的数值仿真计算,探讨应变模态方法用于玻璃幕墙损伤识别的能力。计算结果表明:利用应变模态能够比较精确地识别出玻璃幕墙的损伤位置以及损伤程度。
关 键 词: 损伤力学;玻璃幕墙;动力分析;应变模态;损伤识别

Abstract: The 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 shown that the damage location and extent can be identified accurately by using the strain modal.
Key words: damage mechanics; glass curtain wall; dynamical analysis; strain modal; damage identification
