Structural assessment and finite element modeling of the Volaidai Abdulazizkhan Mosque in the Bukhara region using LIRA-SAPR

Historical monuments and cultural heritage objects play a fundamental role in ensuring the preservation of national identity and cultural continuity. The assessment of their structural condition using advanced computational technologies is an urgent scientific and practical task. This study investigates a XVI-century architectural monument – the Volaidai Abdulazizkhan Mosque located in the Bukhara region. A three-dimensional (3D) finite element model was developed using LIRA-SAPR software, and the structural behavior under static and dynamic loading conditions was analyzed. The stress-strain state, deformation characteristics, and seismic response of the structure were evaluated. The results reveal the presence of localized stress concentrations and deformation zones, particularly in the foundation and dome-wall connection areas. Despite these local effects, the overall structural stability remains within permissible limits. The obtained results provide a reliable basis for assessing structural safety and developing strengthening measures for historical monuments.
