In Turkey, most of the existing buildings have been designed according to Turkish Earthquake codes of 1975 and 1997. It is a well known fact that, poor material quality, poor design, poor control on site and inadequate workmanship makes existing buildings vulnerable to earthquake. In addition, change in function of buildings becomes another problem. These problems increase the importance of assessment of existing buildings. For this purpose, a new chapter has been added to the new code and assessment methods of existing buildings is regulated. 2007 Turkish Earthquake Code offered two analysis methods, linear and nonlinear analysis methods. Due to comprehensive computational, modeling and assessment challenges involved in applying the code procedures that are generally not well understood by practicing engineers, the use of commercial package computer programs is preferred. There are widely used three software’s in Turkey; Idestatik, Sta4 and Probina. These programs currently handle linear assessment method only. This study aims to compare the assessment results of the most widely used three structural analysis and design softwares in Turkey. For this purpose, four v different structures having different property and plan were employed. These buildings were selected to be representative of the mostly common building types. Each building has been modeled and identified with the same material properties, the same reinforcement details and the same geometric properties in each software. The results of the assessment are compared in order to determine the inconsistencies among the software’s and their reliability.

Comparison of seismic assessment procedures in the current Turkish code Okur, Abdullah; Yakut, Ahmet; Department of Civil Engineering (2007) In Turkey, most of the existing buildings are vulnerable to earthquakes due to their poor material quality and inaccurate design. Besides, so many destructive earthquakes occurred in the past, because Turkey is located on a seismically active region. Therefore, existing buildings should be assessed and necessary precautions should be taken before a probable earthquake. To assess seismic performance of the existing buildings, the 2007 Turkish Earthquake Code offers two methods which are linear and nonlinear....
Pros Amd Cons of Assessment Methods in the 2007 Turkish Earthquake Code Şenboz, Ali; Sucuoğlu, Haluk (2009-01-01) A new chapter has been added to the 2007 Turkish Earthquake Code for the assessment and retrofit of existing buildings. The assessment procedures proposed In the Code are classified as linear elastic and nonlinear procedures. A research has been conducted in this study in order to evaluate the differences between the two types of seismic assessment procedures in the 2007 Turkish Earthquake Code. For this Purpose, two residential buildings in their existing and retrofitted states were comparatively assessed ...
3-D soil structure interaction analyses of three identical buildings in Sakarya city after 17 August 1999 Kocaeli earthquake Ünal, Orhan; Çetin, Kemal Önder; Department of Civil Engineering (2003) The aim of this study is to analyze the soil structure interaction of three identical buildings on ®ahinler Street of Sakarya city which had no damage to heavy damage after the Kocaeli (1999) earthquake. For the purpose of 3-D dynamic nonlinear analysis of the soil site and the overlying structures, Flac3D software was chosen as the numerical modeling framework. Soil properties were determined by using the results of available site investigation studies. A three dimensional mesh was created to represent the...
Multistage seismic assessment methods for existing reinforced concrete buildings and their applicability for retrofitting cost estimation Doğan, Onur; Yücemen, Mehmet Semih; Koçyiğit, Ali; Department of Earthquake Studies (2013) When the huge building stock in Turkey is considered, it is practically impossible to carry out detailed structural analyses for all of the buildings. In order to cope with the seismic safety evaluation of a large number of existing buildings, it is necessary to use simplified techniques, which can predict the seismic vulnerability of the existing buildings in a relatively short time. The comprehensive structural data compiled for the 48 different reinforced concrete buildings contain full information on th...
Evaluation of alluvial deposits in Gemlik basin in terms of earthquake codes. Avşar, Ulaş; Doyuran, Vedat; Department of Geological Engineering (2006) Gemlik County is located in the Marmara Region (NW Turkey), which has been affected by destructive earthquakes sourced from North Anatolian Fault System throughout its history. The bulk of the settlement rests on alluvial deposits of the Gemlik pull-apart basin. So, it is vital to investigate the foundation soils in this basin and the response of them to earthquakes. Many earthquake codes were established by the authorities in different countries of the world to estimate the possible ground shaking and seis...
