© 2013 IBRACON This paper proposes an automatic method based on the computing vision, implemented in a mobile platform, to inspect cracks in masonry and concrete. The developed algorithm for image processing performs this task from images of the cracks evolution. The contribution of this paper is the development of a mobile tool with quick response aiming to assist technicians in periodic visit...

The article presents a hybrid monitoring technique for the measurement of the deformation field. The goal is to obtain information about crack propagation in existing structures, for the purpose of monitoring their state of health. The measurement technique is based on the capture and analysis of a digital image set. Special markers were used on the surface of the structures that can be removed...

An experimental study is conducted on three ½ scales, single-story, single-bay, frame specimens. The first specimen was a reinforced concrete frame with solid-brick infill. The second specimen was a reinforced concrete frame with hollow clay perforated-brick infill. The last specimen was a reinforced concrete frame without any infill. These three specimens were tested by pseudostatic method. Di...

This paper concerns the structural identification of historical masonry buildings with reference to a case study, which is discussed in detail. The building is located in Southern Italy (Lecce). It has an ancient vaulted roof that is complex and commonly found in old masonry structures. This study takes advantage of extensive historical and structural investigations of the building. Preliminary...

The mechanics of masonry structures have been for long underdeveloped in comparison with other fields of knowledge, presently, non-linear analysis being a very popular field in research. Masonry is a composite material made with units and mortar, which presents a clear microstructure. The issue of mechanical data necessary for advanced non-linear analysis is addressed first, with a set of recom...

Cathodic protection (CP) has been successfully employed to protect steel-framed masonry buildings from corrosion related damage. When a CP system is installed to protect the structural members, other metallic items which are within the fabric of the structure but are not in direct electrical continuity may suffer from stray current interactions, resulting in accelerated corrosion of the discont...

This paper presents the design of an augmented reality application for the Gothic Silk Market Building called the "Lonja de la Seda" in Valencia (UNESCO Monument Heritage Site, 1996) and the results of the experiments carried out "in-situ" to observe its usability as an accessibility resource. The objective of this project has been to use and validate augmented reality (AR) as a tool to increas...
