作为保障工程安全和研究结构灾变机理的重要手段,结构健康监测为研究基础隔震技术在实际工程应用中的问题提供了技术保证。基于“基础隔震结构健康监测系统的设计与实现(Ⅰ):系统设计”中的设计方法,研究某超长基础隔震结构健康监测系统的总体设计、传感器选型与测点布设、数据采集与传输方案及数据库结构设计,并对该系统已获取的监测数据进行初步分析。分析结果表明,该基础隔震结构健康监测系统协调运行状态良好,能实现其预期功能。基于性能状态评价指标对该结构状态进行评价,表明该基础隔震结构性能状态良好。
As an important means of ensuring the safety of engineering and the mechanism of catastrophic structural disasters, structural health monitoring provides a technical guarantee for the research on the application of base isolation technology in practical engineering. Based on the design method of “the design of system for health monitoring of base-isolated structure” (Ⅰ): System Design, the overall design of the health monitoring system of a long base isolation structure, the selection of sensors and the arrangement of measuring points, Data acquisition and transmission programs and database structure design, and the system has been obtained monitoring data for a preliminary analysis. The analysis results show that the base isolation structure health monitoring system is in good coordination and can realize its expected function. The state of the structure was evaluated based on the performance state evaluation index, indicating that the performance of the basic isolation structure is good.
