“…DIC measurements directly provide contour maps of surface displacements and strains by comparing the digital images of the original and deformed states of the specimen surface. In recent years, 3D-DIC has been extended to various structural applications, including full-scale gusset plate connections (Iadicola 2012), reinforced concrete beams and columns (Dutton et al 2013;Sokoli et al 2014;De Wilder et al 2016), masonry walls (Ghorbani et al 2015;Bolhassani et al 2016), and timber-framed structures (Sieffert et al 2016).…”

Elastomeric bridge bearings are widely used in bridges in order to allow deformations caused by temperature variations, traffic loading, shrinkage due to prestress or aging, and construction misalignments. However, manufacturing imperfections in these bearings (such as deviations in rubber layer thickness and non-parallel steel plates) affect their structural performance. Currently, quality control of these bearings involves destructive testing, which is costly and time consuming. This paper presents an alternative, vision-based approach for assessing the internal structure of elastomeric bridge bearings, which eliminates the need to destroy them. Threedimensional digital image correlation (3D-DIC) is used to estimate the thickness of different rubber layers and any shim rotation or distortion based on deformation patterns on the surfaces of the bearings during compression testing. 3D-DIC provides full-field measurements of displacement and strain on the surface by tracking the distribution of grayscale values of pixelbased subsets in the sequence of stereo images. The presented approach enables engineers to efficiently evaluate bearings for quality control purposes.

“…Quasi-static tests performed on joints, elementary cells, and shear walls were used to calibrate the numerical model used for the one-story traditional timber-framed house (Vieux-Champagne et al 2014b). Seismic tests performed on a full scale wall and one-story house were used to validate the model (Sieffert et al 2016, Vieux-Champagne et al 2017. One-story timber constructions are often used for residential houses, whereas two-story constructions are also suitable for school buildings or hospitals.…”

Due to their seismic resistance, traditional timber-framed structures with masonry infill suffered little damage during recent earthquakes. Moreover, timber-framed structures can be built with reduced costs thanks to the use of locally available materials such as wood, stone, and earth. Based on an experimentally validated numerical simulation for a one-story house, the seismic resistance of a similar two-story house is investigated. A simplified Finite Element Model with linear and nonlinear truss elements is proposed to analyze the seismic resistance of a two-story building. Nonlinear hysteresis constitutive laws are defined only for two majorcomponents of the structure which are assumed to be representative of the global structure behavior: diagonal X-crosses (concentrating the interaction with the infill material) and steel strip connections. These kinds of structures have been overlooked due to a lack of knowledge of their potential behavior in seismic prone area and a lack of building codes and standards for their own design. To promote them, a failure criterion, that might easily be used in engineering studies, is required. This article proposes a simple criterion based on Eurocode 8 to quantify the seismic resistance of one-and two-story houses. The simulation shows that, even in case of high intensity ground motion, the two-story building should not be collapsed. This study may help at designing twostory timber-framed structures in seismic prone areas for (re)construction projects.

“…Digital image correlation (DIC) is a measurement technique that extends the principles of photogrammetry to obtain full-field surface displacement measurements of an object using digital cameras. Several researchers have applied DIC to detect damage to building structures using dynamic responses [11][12][13][14][15][16]. Shih et al [11,12] developed a low-cost digital image correlation method to measure the dynamic response of shear buildings.…”

“…Combe and Richefeu [13] used the DIC technique coupled with geometrical rules to develop an approach to track the nonsmooth trajectory of particles. Sieffert et al [14] presented a digital correlation technique to capture the full-field displacement by using a high-speed camera of a full-scale structure tested on a shaking table.

Frequency response function (FRF) data can provide considerably more information on damage in the desired frequency range as compared to modal data extracted from a very limited range around resonances. Among structural health monitoring techniques, FRF-based methods have the potential to locate structural damage. Conventional structural damage detection technology collects structural response data using contact systems, such as displacement or acceleration transducers. However, installing these contact systems can be costly in terms of labor, cost, and time. Several noncontact measurement technologies, such as optical, laser, radar, and GPS, have been developed to overcome these obstacles. Given the rapid advances in optical imaging hardware technology, the use of digital photography in structural monitoring systems has attracted considerable attention. This study develops a displacement FRF-based approach to locate damage to building structures. The proposed damage location index, CurveFRFDI, improves the sensitivity of SubFRFDI, which is a substructure FRF-based damage location index proposed by Lin et al. (2012). Moreover, the feasibility of applying the proposed approach to locate damage to building structures using displacement measured by a digital camera combined with digital image correlation techniques is also investigated in this study. A numerical example and an experimental example are presented to demonstrate the feasibility of using the proposed approach to locate damage to building structures for single and multiple nonadjacent damage locations.
