Repair and retrofit of Ketchaoua Mosque in Algeria

A comparative numerical analysis of Ketchaoua Mosque, a 17th-century masonry structure in Algiers, Algeria, reveals that its minarets are the most vulnerable components due to their slender design. The study, conducted using finite element method and system identification techniques, highlights the structural challenges posed by seismic events, which have caused damage to the minarets and vaults. Located at the foot of the Casbah Ketchaoua Mosque's rectangular plan with cross-shaped cathedral features presents unique architectural and engineering complexities. The research aims to inform repair and retrofit strategies to enhance the mosque's seismic resilience.
