Observations on the Structural Response of two Historical Structures from Earthquake and Explosion Recordings
Abstract »The blast as a result of the bombing attack that took place in the Sultanahmet Square in Istanbul, Turkey on 12 January 2016 was recorded by the strong motion networks installed in two nearby historical monuments, i.e. the Sultanahmet Mosque and the Hagia Sophia Museum. The 30-channel network in the Sultanahmet Mosque and the 27-channel network in the Hagia Sophia Museum operate in real-time mode recording accelerations. In Hagia Sophia, in addition to accelerometric stations, four two-way tiltmeters are installed. One minaret of Hagia Sophia is also instrumented with accelerometers. In this paper we study the structural response characteristics of two buildings using these two unique datasets. We compare the frequency and time-domain behavioral characteristics observed during the explosion with the ones observed during small-to medium size earthquakes.
