Long-Term Vibration Monitoring of the Sultan Ahmet Mosque in Istanbul
The 400-year-old Sultan Ahmet Mosque, aka the Blue Mosque, is one of Istanbul’s most prominent historical structures. The primary structural system of the mosque consists of the main dome, four main arches and four semi-domes supporting the main dome; four pendentives, four main pillars and the secondary arches and piers that support the semi-domes. The structural health monitoring system in the Sultan Ahmet Mosque was installed in 2012. It consists of ten three-component accelerometers deployed at four different levels within the structure. Istanbul is in a seismically active region of Turkey. Istanbul shores are at about 20 km to the north of the segments of the North Anatolian Fault within the Marmara Sea. The mosque was damaged during the two M7+ earthquakes in 1766 and also in the M7.0 1894 earthquake. Since the deployment of the structural health monitoring system in October 2012, more than 200 earthquakes with local magnitudes varying from 2.1 to 6.6 have been recorded by the sensors in the structure. This paper is about the time-domain and frequency-domain analyses of this data set with the aim of identifying dynamic response characteristics of the structure, its modal frequencies and their dependence on time, earthquake magnitude and ground motion amplitude.
