依托重庆国际博览中心,综合考虑建筑结构的设计特性、周边地质环境、经济等因素,建立了有限元结构模型进行结构力学性能分析。在此基础上通过FBG光纤光栅应力(应变)、温度、静力水准挠度、风速风压等传感器的布置优化设计,构建了长期安全健康监测系统的架构、传输机制、数据处理机制及预警预报系统,为进行大型建筑结构的结构状态识别、结构的承载能力评估等工作奠定了基础。
Relying on Chongqing International Exposition Center, the finite element model is established to analyze the structural mechanics performance considering the design characteristics of the building structure, surrounding geological environment and economy. Based on this, the architecture, transmission mechanism, data processing mechanism and early warning system of long-term safety and health monitoring system are constructed through the optimal layout of sensors such as stress (strain), temperature, static level deflection and wind pressure of FBG. , Which lays the foundation for the structural state identification of large-scale building structures and the assessment of bearing capacity of structures.
