摘　　要：针对某大跨度钢结构人流量大、安全级别较高而引起的对其安全性和可靠性关注,通过对结构建模,找出关键构件并在上面安装振弦式应力应变计和水平位移计,并在部分柱脚安装沉降位移计。通过传感器数据对关键受力结点的应力应变和屋面结点的位移进行结构健康监测,评估该结构是否存在安全隐患,为其安全运营提供依据。Aiming at the safety and reliability concerns of a large-span steel structure with high traffic flow and high safety level,through modeling the structure,this paper found out the key components and installed vibrating wire stress-strain gauges and horizontal displacement gauges on them,and installed settlement displacement meters at some of the column feet.Through sensor data,the stress and strain of key stress joints and the displacement of roof joints were monitored for structural health,so as to evaluate whether the structure has safety risks and provide a basis for its safe operation.
