Item Sistema de monitoreo de salud estructural (SHM) de puentes de hormigon mediante redes WSN(Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Maestría en Telecomunicaciones, 2021) López Naranjo, Saúl Gabriel; Salazar Escobar, Fabián RodrigoThis project designs a structural health monitoring system (SHM Structural Health Monitoring), based on WSN networks to control the integrity, safety and performance of the structure of a concrete bridge through the deployment of several sensors, responsible for constantly recording the vibrations caused by vehicular flow, pedestrian or due to unpredictable events caused by nature, such as earthquakes, high winds etc.. This wireless sensor network has a dynamic architecture, consisting of several stages, first there are the sensors also known as nodes which are located at the most critical points of the structure, the same that are responsible for recording the vibrations during time intervals. Subsequently, the information obtained is transmitted by radiofrequency signals to the central node or Gateway, which is in charge of collecting the information received from the nodes and sharing it with a computer located at the base station. As a result of the monitoring, a strong correlation was found between the length of the bridge and its respective vibration periods, regardless of the thickness of the concrete structure of the bridge. With this research, a baseline or reference line on the behavior of this type of bridges was established, so that in the future there will be a continuous follow-up and updating of the recorded information, with the intention of predicting failures and damages caused either by the vehicular or human flow or due to the environmental forces to which the bridge is exposed.
