Typological And Seismic Code Assessment Of Stone Masonry Walls: The Case Of Safranbolu Houses

Authors : Arslan Büşra . Mutlu Mehmet .

Abstract

Safranbolu has preserved this texture throughout history by developing spatially and stylistically with the contributions of different civilizations along with its unique qualities and determining features. Safranbolu houses, shaped by traditional values, are important heritage elements that bridge the past and the future. Although these buildings have been exposed to various natural disasters over the years, they have managed to largely preserve their architectural integrity. However, it is estimated that these historical structures in Safranbolu, located approximately 65 km from the North Anatolian Fault, are under threat of earthquakes. Especially the stone masonry walls, which are widely used in Safranbolu houses, are known to be more sensitive to seismic effects and carry a great risk in terms of structural integrity. This study aims to examine in detail the compliance of opening ratios in stone masonry walls with seismic design provisions to protect Safranbolu houses and ensure their safe transfer to future generations. Within the scope of the study, the typology and grouping of the ground floor masonry stonewalls of 100 Safranbolu houses built in the 18th and 19th centuries according to the rules specified in the 2007 “Regulation on Buildings to be Built in Earthquake Zones” were analyzed and structural compliance analysis was performed. The structural compliance analysis revealed that 15% of the masonry walls conformed to modern design standards, while 85% did not, and that structural improvements are needed to reduce seismic vulnerability.
