The problem is considered through an example of a real conservation case study of the Yavuz Selim Mosque in Istanbul, dating back to the 16th century. The structure is subjected to gravity and seismically originated forces. FEM analysis is conducted using SAP2000. The behavior of the system before and after retrofitting process is compared. Also, the site observations related to the crack patterns are explained in detail. Numerical results show that external confinement or tightening using steel rings reduces the principal stresses and displacements of the structure significantly and a more distributed stress condition is obtained.
