RESEARCH ON HEALTH MONITORING SYSTEM OF SPACE STRUCTURESBASED ON DISPLACEMENT

摘要

Along with the rapid development and wide application of large-span spatial structures, safety of these structuresrnis becoming a major concern for owners and structural engineers. Frequently reported incidents and accidentsrnhave highlighted the urgent need of continual on-line assessment of the health status of these spatial structures.rnHowever, seldom research work on the health monitoring of space structures has been reported, lots of basicrnwork such as the theory of structural damage detection, the principle of safety evaluation and the equipment ofrnhealth monitoring is still under progress. This paper will mainly discussed some research work on the healthrnmonitoring system of space structures based on displacement.
