Geognostic Investigation on Damage and Deterioration Evolution of Soil and Architectural Materials of Mekaad Radwan, Ottoman Cairo, Egypt (Case Study)

This study determines which factors play roles of deterioration in Mekaad Radwan. The study also makes it possible to know the real response of the masonry structure to the deformation imposed at the base of the foundation condition. The used methodology included the identification of the seismicity situation and the possible damage effects of the Cairo (1992) earthquake through discussion of situation before and after earthquake as well as the controlling factors, in addition to the analysis and determination of the types, geometry of the types, deformation and other deterioration patterns, using the direct observation and primitive monitoring evaluation.
