Earthquake Engineering

Science into Construction

Since 1903, there are more than 130 earthquakes causing damages to our country. As a result of these earthquakes, we lost 110 thousand of our people.

In our country, a total of 600 billion dollars is invested as a physical capital and the total national richness is exceeded 3 trillion dollars. However, it should be remembered that 90% of this amount is under a very serious earthquake risk. In the last 100 years, on the average, every year, we lose 1% of our national income with the earthquakes. As an illustration, we lost 10-15% of our national income by Doğu Marmara (Mw=7.6) and Düzce (Mw=7.1) earthquakes in 40 seconds. In other words, if we could get over these earthquakes as in modern countries, our country would have doubled its current assets.

Istanbul and its close regions are under threat of the Marmara Sea’s active fault systems. In this region, because of the Marmara Sea’s fault system, 8 earthquakes with a magnitude more than 7 were happened in the 20th century. In the last 100 years, this fault is in seismic-silence and on the other hand, there are several cities who are expecting the earthquake risk in the global scale. And it is known that İstanbul is the most unprepared city against earthquakes. Today there is a strong opinion that the earthquake safety of city residential stoke is a common concern in Turkey, especially for İstanbul. All the investigations related to this subject also prove this concern and the importance of this concern is beyond the preliminary predictions.

The countries which can achieve to generate and apply knowledge can reduce the losses due to earthquakes to minimum levels. In these types of countries, researchers and engineers are conducting intense research and development (R&D) activities for reducing the geological risks (such as earthquakes, floods, landslides, foundation/rockmass movements, volcanic eruptions).

Continuous development of Turkey is depending on the reducing the natural disaster risks especially earthquakes. State agencies and private construction companies have very serious roles in order to achieve these targets. For these reasons, Yapı Merkezi is acting sensitively and responsibly and also producing studies related to earthquake engineering. These are summarized below:
