TDV&Bridgestone Joint Project

Bridgestone Corporation and the Turkish Earthquake Foundation have carried out a joint project in order to popularize the use of earthquake insulation systems in residences. The project is aimed to design the most economical isolation unit (isolator) and to determine the most suitable structural system in regions prone to different earthquake hazards in Turkey.

Within the scope of the project, 5-10-15 storey buildings, representing the existing building stock, will be designed as earthquake isolated with traditional methods and a built-in base and high damping rubber elastomer isolation units (high damping rubber bearing - HDRB) and performance and cost comparisons will be made.


TDV-DASK Pre-Pricing Evaluation of Earthquake Insurance


The seismic hazard map of Turkey has been updated within the scope of the UDAP-Ç-13-06 project supported by the Disaster and Emergency Management Presidency (AFAD) and the Natural Disaster Insurance Institution (DASK).

The aforementioned project used the knowledge gained from national (ex: DLH, 2008) and international (ex: GSHAP -; SESAME-; SHARE-; EMME- seismic hazard projects carried out in Turkey in the last 20 years, and the active fault and instrumental earthquake catalog database obtained from the Turkey Seismo-Tectonic Map (MTA General Directorate) project. The historical earthquake catalog has been compiled using the historical earthquake catalogs used in the GEM Historical Earthquake Catalogue (, SHARE and EMME projects. The updated seismic hazard map obtained using the (probabilistic) seismic hazard method based on probability calculations, shows the maximum ground acceleration (PGA), maximum ground velocity (PGV), T=0.2s and T = 1.0s spectral acceleration (Sa) values ??for Turkish land borders. It gives their distribution within the reference rock ground (VS30 = 760 m/s) by taking into account the 43 years, 72 years, 475 years and 2475 years return periods. In this context, there is an update on the earthquake risk (damage / loss) calculated using the Turkey Earthquake Zones map, which has been in force since 1996, and the insurance pricing based on this risk.

Considering the above-mentioned issue, a project called “Preliminary Evaluation of DASK Earthquake Insurance Pricing System according to the Updated Seismic Hazard Map of Turkey” was carried out with a contract signed between the Turkish Catastrophe Insurance Pool (DASK) and the Turkish Earthquake Foundation (TDV).

The project consists of three main phases. The first phase includes an extensive literature review on the structural and financial damage caused by earthquake disasters in the world and the consequent determination of methods for earthquake insurance pricing. The second and third phases are about the pilot applications of the structural and financial damage methods proposed as a result of the literature review in Istanbul and throughout the country and the effects of these studies on the earthquake insurance prices in Turkey.

In a sense, the project has a content that shows the national academic and professional capacity for possible detailed studies to update the DASK earthquake insurance price system.
