Analysis of prestressed anchord tie-back diaphragm wall of el-sebak tower in Misr el-guedida city

Abstract EN

El-Sebak tower in Misr El-Guedida is a building consisting of two garage basements, ground shopping floor, first trading floor, second offices floor, nine residential typical floors and two villas floors with sixteen floors.

This tower was constructed between other nearby buildings, one of them is twenty floors constructed on pile foundation, and others are eleven floors.

The most critical one chosen in this study is a five storey residential building with shallow foundation at a distance 6 meters apart from El-Sebak tower, which has 9.5 meters deep excavation.

The study is directed towards the analysis of the concrete diaphragm wall and its effect on the five story near-by building at different stages of construction.

The numerical analysis is performed using a plane strain finite element analysis assuming Mohr Coulomb elasto-plastic failure model for soil behavior.

The diaphragm wall in-situ measured lateral top displacements are compared with those predicted from the program and it is found that the predicted values are reasonable to a great extent.
