Settlement of a One Floor Building on Soft Clay Beside a Heavy Building

A one floor building was founded on a deposit of normally consolidated soft clay. It was constructed to annex an existing three storey high building founded on piles. After construction, tilting and settlements of the Annexe were detected relative to the existing building. Recorded absolute and differential settlements, monitored over a period of five years, were considerably high. It is shown here that this could be caused by the combined effect of high compressibility, confinement of clay layers and variations in pressure distribution below foundations

Some Aspects on the Falyum-Egypt Earthquake of October 12, 1992

A moderate size earthquake shocked the southern west part of Cairo by 35km at 15:15 P.M. local time on October 12, 1992 causing wide spread devastation leading to loss of many lives and structure damages along the surrounding big cities. The paper describes the behavior of two identical residential buildings constructed on two different site soil conditions. The lesson learnt from the performance differences are highlighted, and some geotechnical and structural aspects are recorded

Geotechnical Characterization of Subsoil Deposits at Cairo

As a result of considering the historical aspects in Cairo subsoil at different stages of its development, soil deposits in the alluvial plain in Cairo area could be identified and classified on their origin into limited number of major types. Their distribution could be produced on maps on which classes of engineering significance are recognized. The boundaries between map units have been drawn separating areas of equal origin and characteristics. Verification of soil profile from field investigation indicated complete agreement with the previous characterization based on theoretical considerations
