·Objective:
This project aims to analyze & design the foundation of the proposed new building (seven story building) of Mr. Yahya Braik in the city of Nablus.
The project site lies to the south of the main Rafidia street in the city of Nablus and is bordered by an existing Amasha building from the east and Ibn Khaldoon street from the south
· Methodology:
Firstly the loads carried by the columns is calculated by using tributary area by using Auto CAD 2007 then the ultimate and service loads calculated.
From the site investigation report then depending on the structure and soil characteristics the isolated and pile footing are designed.
After that the total volume of concrete and the total weight of steel needed for constructing each of pile and isolated footing are calculated then compare between these values and the lowest on is selected for constructing the foundation.
In this project isolated footings with tie beams at the existing reduced level after cleaning of all loose excavated materials and inclusions is used as it is being more economical than the pile footing, & it is recommended to replace the top 5m of soft silty clay beneath the foundations at the south eastern corner with well graded granular materials having plasticity index less than 10.
Note: The settlement of the foundations designed as described above is negligible.
