Abstract

Asset management is an important area in civil engineering. Monitoring deformations and movements of structures is an essential tool for the asset management and condition monitoring. Currently, a range of technologies such as contact (e.g. strain gauges and displacement sensors) and non-contact sensors (e.g. lasers, radars and cameras) is available for monitoring structural response. However, there is a need for low cost systems, which could be used for real life situations and laboratory environments (for teaching and research). This paper presents a novel approach of using smartphones to monitor movements in structures. The low-cost and easy to use hardware (i.e. smartphone) is readily available for the majority of people. The idea is that a smartphone camera is used to monitor specific markers (points of interest) on a structure. Movements of the markers can be obtained and calibrated for accurate movements of the structure. This paper presents results obtained from both lab structures and a full-scale bridge. Results show that the technology is a simple, low-cost and provides indicative and at the same time accurate information about structural response.
