The paper presents a multidisciplinary approach for diagnosing the structural stability of Takiyya Ibrahim al-Gulshani in Historic Cairo using geometric and architectural documentation, field survey, laboratory tests, numerical analyses under static seismic conditions. Takiyya, built during Mamluk period, is an important medieval complex Egypt has undergone multiple renovations. field-testing includes geotechnical geophysical investigations to evaluate properties bearing soil beneath monument. A 3D survey Terrestrial Laser Scanning was employed record Takiyya's geometry. photogrammetry high-resolution images accompanied by in-situ damage were used document cracking levels, stone weathering, identification decay patterns. Laboratory tests conducted assess mineral composition, physical mechanical construction materials enable assessments. Data appraisal integration into drawings mapping degradation patterns preservation state building. documentation procedures combined with experiments then develop model analysis. Three-dimensional finite element simulations employing macro-modelling approaches performed structures various loading conditions, including modelling soil, resulting good agreement recorded structure nonlinear helped identify causes effects current deficiencies. adopted methodologies provided large amounts information, permitting improved understanding existing as-sessment masonry structure.
