Restoration works have been accelerated substan- tially in Turkey in the last decade. Many historical buildings, mosques, minaret, bridges, towers and structures have been restored. With these restorations an important issue arises, namely how restoration work affects the structure. For this reason, we aimed to investigate the restoration effect on the earthquake response of a historical masonry mosque con- sidering the openings on the masonry dome. For this pur- pose, we used the Hüsrev Pasha Mosque, which is located in the Ortakapı district in the old city of Van, Turkey. The region of Van is in an active seismic zone; therefore, earth- quake analyses were performed in this study. Firstly a finite element model of the mosque was constructed considering the restoration drawings and 16 window openings on the Figure 1. Undamaged view of the Hüsrev Pasha Mosque and social dome. Then model was constructed with eight window open- complex. ings. Structural analyses were performed under dead load and earthquake load, and the mode superposition method was used in analyses.
