Non-Destructive Testing for Building Diagnostics and Monitoring: Experience Achieved with Case Studies

Building inspection on site, in other words in-situ examinations of buildings is a troublesome work that necessitates the use of non-destructive investigation (NDT) techniques. One of the main concerns of non-destructive testing studies is to improve in-situ use of NDT techniques for diagnostic and monitoring studies. The quantitative infrared thermography (QIRT) and ultrasonic pulse velocity (UPV) measurements have distinct importance in that regard. The joint use of QIRT and ultrasonic testing allows in-situ evaluation and monitoring of historical structures and contemporary ones in relation to moisture, thermal, materials and structural failures while the buildings themselves remain intact. For instances, those methods are useful for detection of visible and invisible cracks, thermal bridges and damp zones in building materials, components and functional systems as well as for soundness assessment of materials and thermal performance assessment of building components. In addition, those methods are promising for moisture content analyses in materials and monitoring the success of conservation treatments or interventions in structures. The in-situ NDT studies for diagnostic purposes should start with the mapping of decay forms and scanning of building surfaces with infrared images. Quantitative analyses are shaped for data acquisition on site and at laboratory from representative sound and problem areas in structures or laboratory samples. Laboratory analyses are needed to support in-situ examinations and to establish the reference data for better interpretation of in situ data. Advances in laboratory tests using IRT and ultrasonic testing are guiding for in-situ materials investigations based on measurable parameters. The knowledge and experience on QIRT and ultrasonic testing are promising for the innovative studies on today’s materials technologies, building science and conservation/maintenance practices. Such studies demand a multi-disciplinary approach that leads to bring together knowledge on materials science and building science.

Non-destructive examination of stone masonry historic structures-quantitative ir thermography and ultrasonic velocity
Akevren, Selen; Tavukçuoğlu, Ayşe; Department of Building Science in Architecture (2010)
The in-situ examination of historical structures for diagnostic and monitoring purposes is a troublesome work that necessitates the use of non-destructive investigation (NDT) techniques. The methods of quantitative infrared thermography (QIRT) and ultrasonic testing have distinct importance in this regard. The key concern of the study was developing the in-situ use of QIRT for assessment of stone masonry wall sections having different sublayer(s) and failures. For that purpose, the non-destructive in-situ s...
In Situ Lateral Load Testing of a Two-Story Solid Clay Brick Masonry Building
ALDEMİR, ALPER; Binici, Barış; Canbay, Erdem; Yakut, Ahmet (American Society of Civil Engineers (ASCE), 2018-10-01)
The seismic behavior of unreinforced masonry (URM) structures has usually been investigated by conducting laboratory tests. Such efforts, although useful in order to understand the response of single walls or subassemblages, cannot fully mimic the in situ seismic response of masonry buildings. In this study, in situ lateral load testing of a two-story full-scale URM building was conducted. First, forced vibration tests were performed to determine the vibration frequencies of the building. Afterwards, the bu...
Evaluation of approximate nonlinear procedures for observed response of a shear wall structure
Gulkan, Polat; Yakut, Ahmet; Kazaz, Ilker (2005-06-01)
This article presents an analytical study carried out to investigate seismic response of a lightly reinforced stiff shear wall structure subjected to ground motions classified as near- or far-field. A five-story lightly reinforced shear wall model structure that has been studied both experimentally and analytically in the context of a coordinated research project has been employed. Several response parameters were obtained by linear and nonlinear analyses under a suite of 55 ground motion records on firm so...
Spatial information systems for conservation of historic buildings case study : Doğanlar Church İzmir
Günay, Serkan; Bilgin Altınöz, Ayşe Güliz; Restoration in Department of Architecture (2007)
Conservation of historic buildings requires comprehensive and correct information of buildings to be analyzed in conservation decision making process in a systematic and rational approach. Geographical Information Systems (GIS) are advantageous in such cases which can be defined as computer based systems for handling geographical and spatial data. GIS have the potential to support the conservation decision making process with their storing, analyzing and monitoring capabilities. Therefore, information syste...
Fragility based assessment of lowrise and midrise reinforced concrete frame buildings in Turkey
Ay, Bekir Özer; Erberik, Murat Altuğ; Department of Civil Engineering (2006)
In this study, structural vulnerability of reinforced concrete frame structures by considering the countryspecific characteristics is investigated to manage the earthquake risk and to develop strategies for disaster mitigation. Lowrise and midrise reinforced concrete structures, which constitute approximately 75% of the total building stock in Turkey, are focused in this fragilitybased assessment. The seismic design of 3, 5, 7 and 9story reinforced concrete frame structures are carried out according to the ...
