Resumen:
This paper presents the ongoing research related to the development of IoT platformsfor the detection of damage in steel railway bridges. The development encompasses severalfields from sensors, to damage detection, to data transmission, and to the infrastructure managementsystem. The paper introduces the concept of regular availability of up-to-date data setsthrough an Internet-of-Things (IoT) approach that integrates information in cloud-based BIMplatforms. Initial case studies have been developed in routinely performed load tests. Furthermore,laboratory experiences aimed at calibrating numerical methods under a controlled environmentare being developed. Subsequently, complete systems encompassing different parts will be implementedin the form of real-case studies. The steps that have been performed so far include i)measurement of key characterizing data from these structures using different platforms ii) datatransmission using different ranges and platforms iii) damage detection using advanced FE-modelsand iv) understanding the data management platforms and the corresponding interoperability.The ongoing research project includes experiences in a joint effort between academia and industrialpartners. The assessed structures include (but are not limited to) either new or existing steelrailway bridges.
