Yayın Evaluation of wooden structures(Springer, 2019) Koca, GülruIn order to preserve the architectural heritage and sustainability of cities, the accurate evaluation of the mechanical properties of existing buildings is crucial. While inorganic building materials such as natural stones can be evaluated more easily, it is difficult to accurately assess the mechanical properties of wood. Mistaken evaluations of structural wooden members may lead to large-scale replacements in the maintenance and restoration of buildings. The techniques used in the evaluation of wood are; destructive, semi-destructive and non-destructive tests. Although destructive tests give accurate information about the mechanical properties of wood, they are not preferred in the evaluation of the existing structures because they cause the loss of structural integrity. The semi-destructive and non-destructive methods are being widely used for the last decades in the evaluation of structural wooden members. As these techniques do not give harm to the structural members, they allow the in situ evaluation of wooden structures. While semi-destructive tests are carried out with the extraction of a small piece without influencing the mechanical properties of wood, non-destructive techniques are carried out with the help of small devices in order to detect the interior defect and deteriorations. In this study, it is aimed to give information about some of the most used semi-destructive and non-destructive test methods.Yayın New housing trends in Istanbul(Open House Int, 2016-12) Özker, Serpil; Tuğlu Karslı, Hatice UmutExternalization that became prominent in 1980s with the globalization brought along dramatic changes in social and spatial areas. The social, cultural and economic events that took place on an international level thanks to globalization made the impact of change felt which was reflected on the urban space and, therefore, on the house, resulting in an increase in the importance of the residential sector. Externalization and developed economic structure enabled more investments into houses which introduced a concept of housing populated in urban fringes starting from the city centers. The housing concept which was shaped by the impacts of the urban transformation after 1980 turned into a new emerging lifestyle in Istanbul in 2000s. Accordingly, the study aims to establish the position of housing in Istanbul and new meanings formed by the socio-cultural changes. In this sense, housing before and after 1980, globalization, gentrification, urban transformation, spatial segregation, socio-economic and cultural aspects were discussed based on the structural benchmarks, and 4 different housing forms, namely the "Loft", "Residence", "Terraced House", and "Gated Communities", with individual structural examples. This study, thus, aims to question the form of tenancy of these houses created through varying concepts and concerns today. The results obtained showed that the housing as an indicator of cultural life in Istanbul has turned into a lifestyle that is shaped by similar aspects and commercial concern, despite different approaches or production forms, eliminating the traces of the cultural life of the society.
