In Situ Dynamic System Identification of Historic Masonry Monuments Based on Non-destructiveTesting

Istanbul is home to numerous architectural heritage which are in a great variety built by Byzantine and Ottoman period. On the other hand, cultural heritage buildings are faced with serious earthquake risks which require the investigation of the structural behaviour of cultural heritage buildings and the taking of necessary conservation measures to preserve and transfer them to the future in a sustainable way. This article describes an experimental in-situ investigation of an 18th century historic masonry monument, Nur-u Osmaniye Mosque in Istanbul by the non-destructive testing. Dynamic system identification study based on operational modal analysis (OMA) tests which include two different test setups in terms of locations and numbers of accelerometers. The extracted dynamic parameters of structure such as natural frequencies, mode shapes and as well as damping ratios obtained from two different test setups compared. In addition, the results of non-destructive in-situ tests used for the 3D Finite Element (FE) model updating by comparing and calibrating numerical and experimental characteristics. The paper presents an in situ dynamic identification procedure of an historic masonry monument based on operational modal analysis and compares dynamic properties obtained from experimental and numerical studies and gives the results of FE model updating of the structure

Mimari mirasın korunmasında uygulama elemanlarının yetiştirilmesine yönelik yaygın eğitim uygulamaları

Implementation works for conservation and restoration are endeavors that require exclusive specialization and experience, because of the variety of work items, the unexpected challenges that may emerge during implementation and the possible irreversible damages of incorrect interventions. However, in Turkey, - just as in the case of new constructions- inexperienced, and unqualified workers are often being employed on conservation and restoration sites. It is not possible to expect conservation and restoration work of the desired quality with the absence of qualified workers. Traditional building crafts and architectural conservation practises, which in the past used to be transferred from master to apprentice, appear today as a vocational and technical education field. By the end of 2012, 15 vocational high schools and 29 junior technical colleges were operational in Turkey for vocational and technical education in restoration and conservation. Despite the rapid growth in the number of such programs in the past years, vocational and technical education has not fulfilled the expectations and objectives. Vocational and technical training (VET) is a model that is based on the relationship of education, industry and employment. However, the expected correlation of these sectors is not achieved under the present conditions. A solution to the problem of implementation staff in Turkey is pursued over two distinct channels: arrangements for formal education and efforts to improve informal training. Along with projects to improve the education offered at VET schools, efforts are also being spent to train intermediary staff for architectural conservation via informal courses. Within the study, the initiatives of KOREFD (Association of Conservation and Restoration Firms), KUDEB (Directorate for the Inspection of Conservation Implementations) and CEKUL (the Foundation for the Protection and Promotion of the Environment and Cultural Heritage), will be introduced, as informal training programs in Turkey with tendencies of sustainability; the problems regarding the target group, certification, local characteristics and sustainability will be specified; European examples of informal trainings will be introduced, and a new model will be proposed for improving the quality of informal training in architectural conservation in Turkey.Publisher's Versio

The Characteristics of Büyükada as a Cultural Landscape

This paper addresses the cultural landscape characteristics of Büyükada, the largest of Istanbul’s Princes’ Islands, with regard to the universal definition of the content and extent of the cultural landscape, to provide background to the site’s history and its socio-cultural and urban development. It focuses on the relationship between the built and natural environment in terms of vernacular architecture and organic landscape, and is based on survey studies and research conducted as part of a PhD Thesis.[...
