Safeguarding Heritage Under Conflict: Numerical Investigation of the Blast Response of the Aleppo Citadel Minaret

Man-made hazards pose serious threats to the safety and preservation of heritage structures. With armed conflict becoming increasingly prominent, it is urgent to enhance our understanding of how these structures respond under extreme conditions to drive conservation strategies. The Citadel of Aleppo in Syria, placed on the List of World Heritage in Danger in 2013 due to the civil war, tragically exemplifies the vulnerability of cultural heritage in times of conflict. In such a framework, this study focuses on the Minaret of the Ayyubid Great Mosque of the Citadel of Aleppo as a representative masonry tower to investigate the effects of man-made threats. Based on a 3D finite element model built in the Abaqus/Explicit environment, blast scenarios associated with aviation bombs and human-borne improvised explosive devices (IEDs) were simulated. The Conventional Weapons Effects (CONWEP) model was used to assess the structural response to blast pressures, also as a function of charge size, standoff distance, and modelling parameters (mesh size, strain rate). This study’s outcomes provide insights into the potential damage caused by aviation bombs and IED attacks, advancing the understanding of the vulnerability of tower-like masonry structures to such hazards while also informing future conservation strategies.
