A Wireless Multifunctional Structural Health Monitoring System

Abstract

Structural vibrations have a great impact on civil structures. Most of the damage happening to structures that lead to a reduction in their life span is due to vibration. This vibration can be natural or man-made. This paper explains the importance of SHM(Structural health monitoring) and proposes a system for continuously monitoring the structural health status. The prototype consists of an ADXL-335 accelerometer, Arduino Uno, GPS (Global positioning system) and GSM (Global system for mobile communication). The functionalities of the system include detection of variation in the structural parameters, locating the position of the structure by means of GPS and sending the health status of the structure to authority where the GSM consists of a prioritized list of numbers. The paper also focuses on analyzing the dynamic parameters like acceleration and tilt angle in three modes: no vibration mode, normal vibration mode and collapse mode. Also analysis of time-domain features of vibration data in three modes are also analyzed.
