The project:
The site is located in Tulkarem city.
The building consists of seven stories, and the area of each stories is about 700 m2 the aim of this research is to design foundations that are practical and economic.
This project contains :
1-Chapter one: Introduction.
2-Chapter two: literature view .
3-Chapter three: site investigation and soil report.
4-Chapter four: Geotechnical and structural design of foundation.
5-Appendix and references.
Types of foundations :
v Shallow foundations:
Shallow foundations are those founded near to the finished ground surface, generally where the founding depth (Df) is less than 3 m.
Types of shallow foundations:
1. Isolated footing.
2. Combined footings.
3. Continuous footing
4.Strap footing.
5.Mat foundation
Structural system :
As we know any structure consist from elements, these elements can be classified into:
1. Slab.
2. Columns.
3. Beams.
4. Walls.
5. Foundation.
Loads:
} Load calculations:
} The load calculations in this project were calculated by Sap program.
Live load = 400 Kg/ m2
Super imposed dead load = 500Kg/m²
Structural analysis using sap 2000:
} In this project we use sap 2000 to analyze the load and find the reaction at all columns.
} The reaction of footings from column
Site investigation:
} The Site Investigation of the site were studied through comprehensive site investigation, carried out on January 2011 by Hijjawi Engineering laboratories.
} Five boreholes were dug out in site to carry the subsurface investigation
Site description:
The geological report shows that the site consist of moist and plastic formations of soft creamy marlstone within the whole depth of exploration and covered by a thin layer of silty clay
The collected sample was tested for physical and mechanical properties.
