Response of Four Tall and Slender Structures in Istanbul To a Long- Distance Earthquake


Abstract eng:
Large magnitude earthquakes originating from distant sources produce long period waves that potentially travel over long distances without significant attenuation. The resulting ground motions at large distances are long-duration, typically a few minutes minimum and contain waves having long periods. They induce large displacements in high-rise buildings or in structures having similar natural periods of vibration. The 24.05.2014, Mw 6.9 Gokceada earthquake of North Aegean Sea took place at an average distance of 300 km to Istanbul. Among a series instrumented structures and buildings in Istanbul, we take a close look at the response of three tall and slender structures. They are the 62 floor, 238 m high Sapphire Tower, currently probably the tallest building in Europe; the 16th century minaret of the Hagia Sophia Museum, which stands at a height of 73 m; and the 20th century minaret of the Maltepe Mosque, which with its 70 m is the most slender minaret in İstanbul. The displacement response of all of these structures was remarkably long, lasting a few minutes, providing interesting examples of the phenomenon.
