提出适用于大跨度空间结构特点的健康监测及预警系统的组成内容。针对大跨度空间结构大规模、大面积空间布局、静态应力和形变为主、材料性质以钢材为主的特点,从理论、硬件、软件三方面分别介绍大跨度空间结构在复杂荷载与复杂环境作用下的灾变机理,以及建立相应的大跨度结构体系安全性评价标准。适用于大跨度空间结构的新型传感监测设备开发和故障预警集成软件系统的开发。
The component contents of health monitoring and early warning technology are put forward, which can be applicable for large-span spatial structure. Based on the characteristics of spatial structure including large scale, big-area arrangement, static stress and mainly of deformation and steel, the disaster mechanism of large-span spatial structure under complex loads and conditions are introduced from theory, hardware and software. Besides, evaluation standards are established corresponding to large-span structural systems. It is available for the development of new sensor monitoring equipments and fault early waming integration software system.
