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 of proper repair and maintenance works and keeping them for long periods of time with their authentic features. The earthen materials together with neighbouring plaster layers that complement/protect the wall structure were examined in terms of their material properties to better define their roles in traditional timber framed structures. The original mud brick, mud mortar, mud plaster and interior and exterior finishing plasters were collected from some traditional timber frame houses in Güdül and Beypazarı districts of Ankara. Their material characteristics were examined in terms of: (i) physical properties, such as bulk density, particle density, porosity, water vapor permeability (ii) physicomechanical and mechanical properties, such as ultrasonic pulse velocity, and modulus of elasticity (iii) raw materials characteristics, such as binder-aggregate ratio, particle size distribution, silt-clay content, fiber content, clay type and pozzolan content. Mineralogical composition of silt, clay and aggregates were identified by the X-Ray diffraction analyses. The results are expected to reveal the technological properties of the traditional earthen and plaster materials, contributing to their performance and durability characteristics. The knowledge obtained will also be useful to define the specifications for the repair materials compatible with the original ones.

Timber joint design: the geometric breakdown method
Erman, E (Informa UK Limited, 2002-11-01)
A large number of joints are developed as a result of various timber construction techniques, structural efficiency and cultural differences. Many joints are not used because they are not adapted or are inconvenient for modern manufacturing and construction technologies. Nonetheless, this construction heritage can be harnessed and adjusted for contemporary use. Significant cultural and social differences in timber jointing and construction technologies are reviewed. The Geometric Breakdown Method is develop...
Construction techniques of four of traditional ormana houses
Çelik, Gülşah; Gökce, Fuat; Restoration in Department of Architecture (2009)
The subject of the thesis is construction techniques of four traditional Ormana Houses within the wider context of Akseki Region vernacular architecture. The thesis analyses the appropriate methodology and approach for a documentation of construction techniques and details of the traditional houses. As such, it includes the necessary research and analysis that would provide the base for coherent restoration principles and decisions. The thesis includes the historical background of Ormana, detailed descripti...
SEISMIC SHEAR CAPACITY OF REINFORCED MASONRY PIERS
Sucuoğlu, Haluk (American Society of Civil Engineers (ASCE), 1991-07-01)
Masonry buildings have been, and remain, a popular form for economically enclosing space. Whereas such buildings are safe under gravity loads, most are vulnerable to horizontal loads due to earthquakes. Observations following an earthquake and experimental programs have shown that piers between openings are the most vulnerable part of a masonry building, and that the failure of such piers is due in the majority of cases to shear (or diagonal tension). Accordingly, the study described concerns the seismic...
Forced Vibration Testing and Finite Element Modeling of a Nine-Story Reinforced Concrete Flat Plate-Wall Building
Çelik, Ozan Cem; Sucuoğlu, Haluk; Akyüz, Uğurhan (SAGE Publications, 2015-05-01)
Tunnel form buildings, owing to their higher construction speed and quality, lower cost, and superior earthquake resistance over that of conventional reinforced concrete buildings, have been widely used for mass housing, urban renewal, and post-earthquake reconstruction projects all over the world as well as in Turkey. However, there have been few dynamic tests performed on existing buildings with this structural system. This study investigates the dynamic structural properties of a typical nine-story reinf...
Engineering geological properties and durability assessment of the Cappadocian tuff
Topal, Tamer (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. T...
