“…Such structures were initially built as temporary buildings used for military purposes. Direct adaptation of this technology for civil purposes, combined with extending the lifetime and changing of environmental conditions, have caused design problems, especially in terms of stability and load transfers [1][2][3]. In order to ensure safety and proper operational parameters during lifetime, hybrid experimental-numerical methods are being used in design and exploitation stages [4].…”

“…Therefore, we can observe increasing use of the full field optical measurement methods for determination of displacements and deformations in critical areas of objects, for advanced evaluation of numerical models [5,6]. In the case of measurement of large engineering structures, the most commonly used technique is Digital Image Correlation (DIC) method [1,7]. This method is characterized by scalability of sensitivity and dimensions of fields of view [8].…”

Many building structures due to complex geometry and nonlinear material properties are difficult to be analyzed with FEM methods. A good example is a self-supporting metal plates structure. Considering uncommon geometry and material characteristic of a metal plate (due to plastic deformations, cross section of a trough, a goffer pattern), the local loss of stability can occur in unexpected regions. Therefore, the hybrid experimental-numerical methodology of analysis and optimization of metal plates structures has been developed. The methodology is based on three steps of development and validation of a numerical model with utilization of Digital Image Correlation measurements. In each step, the measurements are performed in different environments, with different accuracies and different scales. In this paper, the results of analysis performed with Digital Image Correlation, that enabled development and validation of FEM model are presented. The performed modification of a measurement setup is also described.

Abstract. The paper presents problems related to the numerical modeling of profiled steel sheets used as self-supporting arch structures for roof covering. The rules of preparing and full analysis of a set of numerical models of these elements with a different level of complexity are given. The models are evaluated by comparing numerical results with the results of extended experimental tests performed by 3D Digital Image Correlation (DIC) method. For each model the comparison of numerical and experimental results has been made for samples of a single-wave trapezoidal profile with corrugated web and lower flanges subjected to compression and bending. The full-field analysis allows to determine the allowed simplification of numerical models which do not affect in significant way the reliability of the results. The proposed methodology is the first step in the development of full assessment methodology for different types of self-supporting arch structures produced by ABM technology.

In this paper a vision-based method for measuring vertical deflection of large engineering structures under load is presented in example of crane working arm deflection measurements. The deflection is computed by means of a digital image correlation technique embedded in the vision-based system. The results of measurements performed on the vision system were compared with data obtained using a Leica Laser Tracker system. The comparison revealed proper functioning of the developed vision system in industrial conditions. Zusammenfassung: Dieser Beitrag präsentiert ein bildgestütztes Verfahren zur Messung der vertikalen Auslenkung großer technischer Strukturen unter Belastung am Beispiel von Auslenkungsmessungen eines Kranarms. Die Auslenkungsbestimmung basiert auf digitaler Bildkorrelation. Die mit dem Bildverarbeitungssystem erzielten Messergebnisse wurden mit Daten eines Leica-LasertrackerSystems verglichen. Der Vergleich zeigt die geeignete Funktionsweise des entwickelten Systems unter industriellen Bedingungen.
