Engineering geological properties and durability assessment of the Cappadocian tuff

1997-08-14
Some of the unique landforms, the so-called ''fairy chimneys'', which were formed within the Cappadocian tuff of central Turkey, were used as dwellings in the past and contain culturally valuable wall paintings. However, these structures are undergoing chemical and physical deterioration due to atmospheric effects. For conservation studies, an understanding of the engineering geological properties of the tuff is essential. In this study, emphasis is placed on both material and mass properties of the tuff. These properties are evaluated for the assessment of rock durability. This study shows that the Cappadocian tuff is almost fresh, with local discoloration, is moderately weak to very weak. and has low unit weight, very high porosity, and high deformability. Discontinuity surveys revealed two dominant joint sets, which not only controlled the formation but also control the structural stability of the fairy chimneys. Various methods used for the durability assessment of the Cappadocian tuff indicate poor to very poor durability. Due consideration must be given to strength reduction due to moisture, poor to very poor durability, and the adverse effects of joints on the structural stability of the fairy chimneys.

Seismic Resistance Evaluation of Traditional Ottoman Timber-Frame Himis Houses: Frame Loadings and Material Tests
Aktas, Yasemin Didem; Akyüz, Uğurhan; Türer, Ahmet; Erdil, Barış; Şahin Güçhan, Neriman (SAGE Publications, 2014-11-01)
Traditional Ottoman timber-frame houses ("himis") form the major part of the cultural heritage structures in Turkey. There are many studies in the literature regarding the seismic performance of himis houses, which claim that these structures have an inherent seismically resistant property. However, these studies lack a quantitative engineering approach and are based on observations made after contemporary earthquakes. This study presents the results of the seismic resistance evaluation of traditional Ottom...
Improved methodology for identification of Goktepe white marble and the understanding of its use: A comparison with Carrara marble
Wielgosz-Rondolino, Dagmara; Antonelli, Fabrizio; Bojanowski, Maciej J.; Gladki, Marcin; Göncüoğlu, Mehmet Cemal; Lazzarini, Lorenzo (2020-01-01)
The provenance of marbles used for ancient statuary and architecture is of utmost importance for archaeologists, art historians and archaeometrists. The aim of this paper is to provide a comprehensive characterisation of the white marble exploited in antiquity in Goktepe (Mugla Province, Turkey) to increase the reliability for identifying this marble in ancient artefacts. A campaign of interdisciplinary archaeological and geological fieldwork undertaken by the Marmora Asiatica project is based on a multi-me...
CALCAREOUS NANNOFOSSILS FROM THE LATE JURASSIC EARLY CRETACEOUS OF NORTHWEST ANATOLIA, TURKEY
Altıner, Sevinç (Wiley, 1993-12-01)
Within the framework of an integrated stratigraphy, a detailed biostratigraphic study of Late Jurassic-Early Cretaceous (Tithonian-Valanginian) calcareous nannofossils was carried out in north-west Anatolia, Turkey.
Material Characterization of Mudbrick and Neighbouring Plasters in Traditional Timber Framed Structures
Erdil, Meltem; Madani, Nigar; Alam, Burhan; Tavukçuoğlu, Ayşe (null; 2017-07-06)
The 19th century timber dwellings reflect the experience of the past on materials and construction technologies of the traditional timber frame structures in Anatolia. However, those houses suffer mostly from wrong repairs due to incompatible materials and inappropriate construction detailing. Wrong repairs introduce and/or accelerate many problems, such as moisture problems, salt decay, thermal and structural failures. Comprehensive studies are, therefore, needed to improve the knowledge for the planning o...
Durability assessment of the basalts used in the Diyarbakr City Walls, Turkey
Dursun, Felat; Topal, Tamer (Springer Science and Business Media LLC, 2019-08-01)
The Diyarbakr City Walls (DCW), which were recently added to UNESCO's World Heritage List, are among the largest and one of the most impressive monuments from ancient times. The history of the DCW stretches back more than 4000 years, therefore making the extant City Walls a combination and reflection of influences of the various civilizations that settled in the region. Basalts having such different textural properties as massive and vesicular were employed as the principal material in the construction of t...
