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 seismic loads which may act on buildings. In this study, Turkish Earthquake Code (TEC-1998) and Eurocode-8 (EN-1998) have been utilized. The analyses showed that EN-1998 results in more conservative estimates relative to TEC-1998, in terms of spectral ordinates. The source of difference between TEC-1998 and EN-1998 has been investigated and three possible reasons have been identified. The variation is probably due to the different seismic characteristics of Turkey and Europe, different soil amplification levels defined by the codes, and different soil classification procedures of the codes.

Seismic Protection of Museum Collections: Lessons Learned After the 1999 Earthquakes in Turkey
Ertürk, Nevra (Middle East Technical University, Faculty of Architecture, 2012-6-1)
Turkey has a long history of large earthquakes in three major fault zones that place two-thirds of the country. Following the two major earthquakes that struck the nortwestern part of Turkey in 1999, several attempts have been taken at hospitals, schools or administrative buildings. The two earthquakes prompted museum professionals and policymakers to consider measures to protect museum collections as well as buildings against earthquake. After the 1999 earthquakes, various projects, scientific researches, ...
Generalized fragility curves for earthquake insurance premiums
Ekici, Melis Aysun; Yakut, Ahmet; Kestel, Sevtap Ayşe; Department of Earthquake Studies (2015)
Since there are three major earthquake lines on Anatolia which are North Anatolian Fault, East Anatolian Fault and West Anatolian Fault, earthquake is one of the most important issue for Turkey. Following the damages of Kocaeli (1999) Earthquake to our economy, importance of earthquake insurance was understood and therefore Compulsory Earthquake Insurance was put into action. However, for the calculation of insurance premiums which were specified by Turkish Catastrophe Insurance Pool (TCIP), only type of bu...
ENGINEERING EVALUATION OF THE 1 OCTOBER 1995 DINAR EARTHQUAKE (ML=5.9)
Sucuoğlu, Haluk; Ergunay, Oktay; Gencoglu, Sinan (1997-01-01)
In 1995, a swarm of earthquakes affected the city of Dinar, Turkey, which is located in Southwest Anatolia and has a population of 35 000. The mainshock having a local magnitude of 5.9 occurred on 1 October 1995. It was preceded by foreshocks in the previous four days, the largest one with a magnitude of 4.7. These foreshocks initiated structural damage in many buildings, which was then severely aggravated by the mainshock and a strong aftershock two hours later, with a magnitude of 5.0. Numerous aftershock...
Civil society and the state: Turkey after the earthquake
Jalali, R (2002-06-01)
On 17 August 1999 Turkey was hit by a massive earthquake. Over 17,000 lives were lost and there was extensive damage to Turkey's heartland This paper examines how various public and private institutions, including state and civil society institutions such as NGOs and the media responded to the needs of earthquake survivors. It documents the extensive involvement of NGOs in the relief efforts immediately after the disaster and examines the impact of such participation on state-civil society relations in the ...
Comparison of mean site-specific response spectra in Turkey with the design spectra of AASHTO
Mestav Sarıca, Gizem; Askan Gündoğan, Ayşegül; Department of Civil Engineering (2014)
Seismic design of bridges is a significant problem for all seismically-active countries including Turkey which has gone through recent destructive earthquakes. Bridges are important elements of transportation and their robustness is important in the aftermath of major earthquakes. Turkish engineers currently employ a modified version of AASHTO (American Association of State Highway and Transportation Officials) LFD Design Specifications for bridge design. Within the scope of a national project (TÜBİTAK 110G...
