In this study we address the question that concerns the shape of the original dome of Hagia Sophia in Istanbul, built by the two great architects, through two approaches. The first is through tests performed on the structural model. By means of this

Structural studies to determine the earthquake worthiness of Hagia Sophia in Istanbul have proved that the monument's static and dynamic behavior depends very strongly on the mechanical, chemical and microstructural properties of the mortars and bric
