Instrumentation and Control of the Behaviour of Structures
Luis Carlos P. Silva Filho, UFRGS, Porto Alegre, RS, Brasil
ABSTRACT The future and continued economic growth of our country is closely linked to the strength and reliability of our nation's infrastructure. Recent advances in NDT and NDE methods are offering new opportunities for continuous and even on-line monitoring of the behaviour of these structures. Traditional techniques like strain gages can now be associated with the use of fibre optics sensors, embedded sensors and combined with information about the homogeneity obtained through radar, infrared or resonance frequency methods. A line of research to investigate the methodological aspects related to the use and interpretation of the results obtained has been established at LEME. The investigation has shown that some care is necessary to ensure the adequate installation and operation of permanent NDT sensors and the combination of NDT methods are vital for the reliable assessment of the conditions of structures in use. The work discusses these various aspects and provides a broad view about the future prospects of this kind of control on the performance of infrastructure elements such as industrial buildings and bridges.Key words: pre-service and in-service inspection, condition monitoring, maintenance
