大跨空间钢结构用体育场健康监测系统的整体设计

Overall Design of Stadium Health Monitoring System for Long-span Spatial Steel Structure

大跨空间钢结构是工程技术领域广泛采用的新型结构形式,但是到目前为止,在大跨钢结构建筑的监测领域方面,仍然未形成完善的体系,以包头体育场为对象进行了结构健康监测系统设计的研究,设计了一套符合包头体育场实际情况的结构健康监测系统。通过监测数据得出主桁架的温度-应力变化曲线,杆件的轴力和弯矩的数据分析,得出现阶段体育场主桁架的工作状态。

Large-span steel structure is a new type of structure widely used in the field of engineering technology,but so far,in the field of monitoring of large-span steel structure buildings,there is still no complete system.Taking Baotou stadium as the research object,the design of structural health monitoring system is studied,and a set of structural health monitoring system which conforms to the actual situation of Baotou stadium is designed.The temperature-stress curves of the main truss were obtained from the monitoring data,and the axial force and bending moment of the bar were analyzed,and the working state of the main sports truss in the stadium was obtained.
