[:es]Una monitorizaci\u00f3n continua de la integridad estructural de los edificions podr\u00eda ayudar a detectar su envejecimiento prematuro o posibles da\u00f1os sufridos y orientar un plan de mantenimiento adecuado teniendo. Estas t\u00e9cnicas Monitorizaci\u00f3n de la Salud Estructural (SHM \u2013 Structural Health Monitoring<\/em>) pueden incluir un dispositivo registrador de datos (data logger<\/em>), varios sensores y una cierta capacidad de procesado. El an\u00e1lisis de vibraciones en una evaluaci\u00f3n estructural, haciendo uso de aceler\u00f3metros (entre otros tipos de sensores), permite medir la respuesta estructural y detectar cambios en los par\u00e1metros modales (frecuencias naturales, relaciones de amortiguamiento y formas modales), dando pistas sobre la existencia de alg\u00fan tipo de da\u00f1o estructural.<\/p>\n\n\n\n

En esta l\u00ednea de investigaci\u00f3n se trabaja en el dise\u00f1o, desarrollo y pruebas de un sistema de SHM de bajo coste basado en aceler\u00f3metros triaxiales MEMS (Micro Electro-Mechanical Systems<\/em>). Se trabaja en el desarrollo de un nuevo sistema de control compuesto por una plataforma myRIO, gestionada por un software espec\u00edfico LabVIEW, que tambi\u00e9n es el encargado de calcular las funciones de respuesta en frecuencia para el posterior an\u00e1lisis modal.[:en]<\/p>\n\n\n\n

Continuous monitoring of the structural integrity of buildings could help to detect premature aging or damage and guide an appropriate maintenance plan. These Structural Health Monitoring (SHM) techniques may include a data logger, several sensors and some processing capability. Vibration analysis in a structural assessment, using accelerometers (among other types of sensors), allows measuring the structural response and detecting changes in modal parameters (natural frequencies, damping ratios and modal shapes), giving clues about the existence of some kind of structural damage.

In this line of research we are working on the design, development and testing of a low-cost SHM system based on MEMS (Micro Electro-Mechanical Systems) triaxial accelerometers. We are working on the development of a new control system composed of a myRIO platform, managed by a specific LabVIEW software, which is also in charge of calculating the frequency response functions for the subsequent modal analysis.[:]<\/p>\n\n\n\n
