IoT sensing of concrete surface strain induced by fatigue loading tests on a simulated specimen of RC slab

Abstract

This paper reports on the application of an inexpensive and simple IoT sensor for strain measurement in structures to monitor deterioration and damage in maintenance. The IoT sensor is a Raspberry Pi, which is available at low cost. In this paper, the strain generated by the fatigue test was acquired by the IoT sensor and a data logger, which is an existing measurement method, and the data of both were compared and evaluated. As a result, the strain value and behavior by the IoT sensor were almost the same as those by the data logger, and it was confirmed that the IoT sensor is effective for quantitative understanding of dynamic deformation in maintenance management.
