摘要/Abstract

摘要： 针对玻璃幕墙结构胶老化、失效以及高风压载荷导致的玻璃脱落等安全事故问题，提出了一种基于光纤光栅传感技术检测玻璃幕墙边缘动态应力变化的方法，构造了玻璃面板边缘应变与结构胶之间的多模态耦合模型，从而预测玻璃幕墙结构安全状况.通过对比分析多模态应变的仿真与实验结果数据可以得到：准分布光纤光栅能够给出结构胶的失效位置，提前对玻璃幕墙结构胶的健康状况进行安全性能评估与反馈.由此可及时更换处理失效玻璃，减少玻璃幕墙脱落事故，在减少经济损失的同时提升了玻璃幕墙的安全性，具有实际价值.

Abstract: Address to safety accidents problems of glass curtain wall such as glass drop induced by structural adhesive failure and aging or high wind pressure load, we put forward a kind of edge dynamic stress detection method based on fiber Bragg grating sensing technology. We construct a multimode coupling model between glass panel edge strain and structural glue for predicting the structure safety of glass curtain wall. By comparing and analyzing the simulation and experimental data of multimodal strain, it can be obtained that the quasi-distributed fiber Bragg grating can indicate the failure position of the structural glue, and evaluate and feedback the safety performance of the structural glue of glass curtain wall in advance. It is of practical value to timely replace insecure glass, reduce the falling accidence of glass curtain wall, reduce economic loss and improve the safety of glass curtain wall.

Key words: glass curtain wall strain field, multimode coupling, finite element analysis, fiber grating technology, safety assessment
