Impact of environmental based effects on SHM strategies

摘要: Environmental based perturbations influence significantly the ability to identify structural dam-age in Structural Health Monitoring. Strategies are needed classify such effects and consider them appropri-ately SHM. It has be considered if seasonal just mask response or temperature itself correlates a weakening of structure. Various methods have been developed analyzed separate environmental from damage induced changes measures. Generally, two main approaches emerged research activity this fields: (a) statistics-based tools analyzing patterns data computed parameters (b) methods, utilizing model bridge considering as well damage-based stiffness values. With background increasing affordability sensing computing technology, effort should made increase sensitivity, reliability robustness proce-dures, separating caused SHM The contribution describes an attempt evaluate both general strategies, their advantages drawbacks. In addition, vibration moni-toring procedures introduced, allowing for temperature-based monitoring data.
