Enhancing seismic performance of historic mosques through retrofitting measures
Abstract Historic mosques are structures that are highly sensitive to seismic events. Strengthening these buildings, which have been exposed to earthquakes throughout history, and ensuring their safe transfer to future generations is crucial. This research study focuses on three significant historic mosques in the eastern province of Türkiye, Erzurum. Their seismic performance, which has not been extensively studied in the existing literature, is investigated using finite element analysis. Dynamic analyses are conducted, utilizing seismic records from notable earthquakes that have caused significant damage to historic mosques in Türkiye, including the 1992 Erzincan, 1997 Düzce, and 2023 Kahramanmaraş earthquakes. As a result of dynamic analyses, the seismic vulnerability of the considered mosques has been determined. These vulnerable areas include the junctions of load-bearing walls, the dome ring, and the main dome. Based on these findings and considering recommendations from the literature, cost-effective and practical retrofit strategies are proposed to enhance the seismic performance of the mosques. The proposed strengthening aims to improve the interaction between load-bearing walls (diaphragm effect) and reduce displacements in the dome. Dynamic analyses are performed using the retrofitted models to assess the effectiveness of the proposed retrofit measures. These assessments were made considering displacements obtained from the dome and walls and the distribution of global damage. The results of 18 dynamic analyses confirm the efficacy of the suggested retrofit configurations in mosques featuring square plan layouts and single dome architectural styles.
Highlights The effect of strong ground motions on historical masonry mosques are studied. There is a retrofit proposal for historical mosques. Structural damage of historical masonry mosques with time-history analyses are summarized.
