数智化视角下建筑结构在动态荷载中的损伤监测

Damage Monitoring of Building Structures under Dynamic Load from the Perspective of Digital Intelligence

科技的快速发展,使得工程结构向复杂化、超大化的方向发展。建筑工程结构的使用寿命可达数十年至数百年。但由于受到环境侵蚀、材料性能退化、长期负荷的疲劳效应和突变效应等灾害因素的共同作用,必然会出现结构和系统损伤的增加与抗力衰减,从而使结构抵抗自然环境的能力下降,在极端情况下甚至可能引发灾难性的事故。因此文章广泛借鉴了国内外有关建筑结构损伤监测的研究成果,并构建了一套集结构监测、损伤诊断和结构评估于一体的综合监测系统,其检测对象包括荷载监测、几何变形监测、结构响应监测等,并将融入建筑信息化技术,实现结构健康监测数据的有效共享与可视化,从而推动建筑领域向智慧城市发展。

With the rapid development of science and technology,civil engineering structures are also developing in the direction of complexity and super-size.The service life of building engineering structures is up to decades,or even hundreds of years.The combined action of environmental erosion,material performance aging and long-term effects of load,fatigue effects and sudden changes,and other disaster factors will inevitably lead to the accumulation of damage and resistance attenuation of structures and systems,and even cause catastrophic accidents in extreme conditions.Therefore,we have extensively studied the research results of building structure damage monitoring at home and abroad,and conceived a comprehensive monitoring system integrating structural monitoring,damage diagnosis and structural assessment.Its detection objects include load monitoring,geometric deformation monitoring,and structural response monitoring,and so on.It is integrated into the building information technology to realize the effective sharing and visualization of structural health monitoring data,thereby promoting the development of smart cities in the construction field.
