Strong-motion instrumentation of Aya Sofya and the analysis of response to an earthquake of 4.8 magnitude M. Erdik, E. Durukal, 6. Yiiziigullu, K. Beyen, U. Kadakal Bogazigi University, Kandilli Observatory and Earthquake Research Institute, Department of Earthquake Engineering, 81220 (Jengelkoy, Istanbul, Turkey ABSTRACT The earthquake response of the Aya Sofya is analyzed on the basis of the strong motion data recorded by the accelerometer network installed on the structure. The modal vibration frequencies and the mode shapes obtained through the use of empirical transfer functions are compared to those based on the ambient vibration survey and the analytical finite element studies. INTRODUCTION Dedicated in 537, after five years of construction, Aya Sofya has been an inspiring architectural and engineering marvel throughout the ages [1, 2]. The Anatolian architects, Anthemius of Tralles (today Aydin) and Isodorus of Miletus (today Milet) created a building that remained as
