摘　　要：非对称大跨钢结构连廊因它独特的结构形式和复杂的受力特性,易受到环境、荷载等多种因素的影响,从而产生结构损伤,但对此类型的结构缺少完整的健康监测体系研究和应用。文中依托明湖国际科创中心钢结构连廊项目,通过对比不同有限元软件计算得到准确有效的有限元数值模拟分析结果。结合结构模态信息的选取,使用多类型、精确的传感器和数据采集设备,对结构提升阶段和卸载阶段进行施工全过程监测。在物联网基础上设计结构健康监测系统,能够实现模型、数据可视化,具有全面的健康监测功能。不仅保障了当前工程的施工和运营安全,也为其他类似工程提供了可借鉴的经验。Due to their unique structural form and complex force characteristics,asymmetrical large-span steel corridor structures are susceptible to various factors such as environmental conditions and loads,leading to potential structural damage.However,there is a lack of comprehensive research and application of health monitoring systems for this type of structure.Relying on the steel corridor project of the Minghu international sci-tech innovation center,this study compares different finite element software to obtain accurate and effective numerical simulation results.By selecting appropriate structural modal information and utilizing multiple types of high-precision sensors and data acquisition devices,a comprehensive monitoring process was conducted throughout the entire construction,including the lifting and unloading phases.Based on the internet of things(IoT),a structural health monitoring system was designed to enable model and data visualization while providing comprehensive health monitoring capabilities.This system not only ensures the safety of construction and operation for the current project but also serves as a valuable reference for similar engineering applications.
