“…2), whereas the latter promotes the controlling computers as the main elements of the structure, as they hold the schedule of measurements, monitor safety parameters and further archive the incoming data in the database or, in case it is unavailable at the moment, store it locally. Below we describe in details the sensors which had not been presented in more details in our previous work [5]. …”

“…The sensor chosen for a specific task has to have the matched functionality, field of view and sensitivity. Often such requirements are not easy to fulfill and therefore the hierarchical system with several sensors which have increasing sensitivity with decreasing field of view had been proposed [5]. In section 2 we present the general scheme of such hierarchical monitoring system and the optical measurement methods implemented.…”

In this paper a distributed intelligent system for civil engineering structures on-line measurement, remote monitoring, and data archiving is presented. The system consists of a set of full-field optical displacement sensors connected to a controlling server. The server conducts measurements according to a list of scheduled tasks and stores the primary data or initial results in a remote centralized database. The description of an exemplary set of full-field sensors including IP and thermovision camera, 2D and 3D digital image correlation systems, and grating interferometry based extensometers is provided. Three different measurement tasks performed by means of this systems are presented in details.

“…The application of these sensors [14] forces engineers to prepare superfine numerical models and predict crucial points to be monitored, which in many cases is difficult or impossible. Sometimes monitoring is performed by a hierarchical system of full-field methods [15,16], which includes interferometric and noncoherent image-based methods (moire fringe method, fringe projection, digital image correlation) [17,18]. However, even if the more efficient, full-field techniques are applied, SHM systems are still too expensive to be applied to monitoring of existing low-cost building structures in the course of their utilization.…”

Application of Hybrid FEM-DIC Method for Assessment of Low Cost Building Structures

et al. 2012

In this work pre-operating tests of low-cost building structures have been presented. A hybrid experimentalnumerical methodology has been used to determine the influence of an external, environmental load on the overall endurance of a hangar made of self-supporting metal-plates. Numerical simulations carried out on a FEM model have been consequently verified by measurements of the structure performed with the 3D Digital Image Correlation method and as a result, a detailed, calibrated FEM model of the structure has been developed.

“…highway truss bridge over Mississippi in Minneapolis, USA, 2007; railway bridge over Malahide estuary near Dublin, Ireland, 2009, makes it desirable to develop an automatic, relatively cheap and reliable monitoring system. The initial attempt to use hierarchical monitoring system based on visual methods is presented in [6]. The realization of such a system is the main aim of the MONIT project, being carried out in Poland [7].…”

Abstract. The Digital Image Correlation (DIC) technique enables full field, noncontact measurements of displacements and strains of a wide variety of objects. An adaptation of the DIC technique for monitoring of civil-engineering structures is presented in the paper. A general concept of the complex, automatic monitoring system, in which the DIC sensor plays an important role is described. Some new software features, which aim to facilitate outdoor measurements and speed up the correlation analysis, is also introduced. As an example of application, measurements of a railway bridge in Nieporet (Poland) are presented. The experimental results are compared with displacements of a FEM model of the bridge.
