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 topographic and geometric constraints of the problem. Linearly elastic perfectly plastic constitutive model was implemented to model the soil behavior. The results of 3-D dynamic numerical analyses in the forms of acceleration, displacement, strain, stress and pore pressure were presented. The higher acceleration, strain and stress levels calculated under the collapsed building can be attributed as the major cause of poor performance of the structure.

An Assessment of the relationship between the local site effects and the distribution of damage in the city of Yalova (Turkey) during 17 August 1999 İzmit earthquake
İlhan, Cemal; Bakır, Bahadır Sadık; Yılmaz, Mustafa Tolga; Department of Civil Engineering (2015)
The relationship between the local site effects and the damage distribution at the City Centre of Yalova after 1999 İzmit earthquake is investigated. The spatial distribution of building damage is presented by compiling the damage statistics reported after the event. It is observed that structural damage at the coastal areas and the ridges were limited. The most severe damage, however, was observed on Hacımehmet Basin and on the west side of Bağlarbaşı Quarter. Peak ground acceleration during the earthquake...
Buildings under recurring near-field earthquakes
Beyhan, Bayhan; Gülkan, Polat; Yakut, Ahmet; Department of Civil Engineering (2010)
Prior to this study, to our best knowledge, no cast-in-place, older-type RC building has ever been subjected to near-field strong ground motions from three major earthquakes. This happened in an indirect way in Turkey over a time span of eleven years. Three identical buildings belonging to Ministry of Public Works and Resettlement (MPWR) that had been built to the same design templates, experienced March 13th 1992 Erzincan earthquake in Erzincan, November 12th 1999 Düzce earthquake in Bolu and May 1st 2003 ...
Prediction of potential damage due to severe earthquakes
Yücemen, Mehmet Semih; Pay, AC (2004-01-01)
A statistical model is developed to estimate the seismic vulnerability of low- to mid-rise reinforced concrete buildings. The model is based on a novel utilization of the discriminant analysis technique of multivariate statistics. Number of stories above the ground level (N), soft story index (SSI), overhang ratio (OHR), minimum normalized lateral stiffness index (MNLSTFI), minimum normalized lateral strength index (MNLSI) and normalized redundancy score (NRS) are selected as the basic estimation variables....
Comparative study of commercial structural analysis programs in view of seismic assessment procedures in Turkish earthquake code 2007
Yıldırım, Suat; Akyüz, Uğurhan; Yakut, Ahmet; Department of Civil Engineering (2011)
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 method...
Structural rehabilitation of damaged RC buildings after the 1 october 1995 Dinar earthquake
Wasti, ST; Sucuoğlu, Haluk; Utku, M (2001-04-01)
This paper contains technical information related to the Dinar project for the rehabilitation of moderately damaged reinforced concrete buildings after the 1 October 1995 Dinar earthquake. The structural appraisal of the damaged buildings, analytical studies leading to decisions regarding structural rehabilitation or demolition, the supervision on site of the rehabilitation and the overall coordination of the project was entrusted to the Middle East Technical University Earthquake Engineering Research Cente...
