An-Najah National University Faculty of Engineering Civil Engineering Dept. Graduation Project Design of Foundation for Residential Building By : 1.A’laa Sabobeh 2.Mohammad Sawallha 3.Mohammad Ali Saleh Supervisor: Dr.Isam Jardaneh Agenda Introduction Types of Foundation Design Single Footing Design Tie Beams Design Pile Foundation Conclusion Introduction The foundation of structure is defined as that part of the structure in direct contact with the ground, which transmits safely the load of the structure to the ground. Introduction This means that the foundation is a primary part in any structure. So that the foundation must be designed in a perfect way. The foundations in this project are classified into two alternatives: Shallow Foundation (Single Footing). Deep Foundation (Pile Foundation). Single Footing We decided to use this type of foundation due to two main reasons: Bearing capacity is relatively high (400KN/m2). Total area of footing < 60% area of building. Pile Foundation Pile foundation used because an adequate bearing capacity can't be found at shallow enough depths to support the structural loads. Design for Single Footing In the Beginning we divide the columns for tow groups depends on the loading. Grouping Joint # OutputCase CaseType StepType F3(fixed) F3(pin) Area Req.

Tie Beams, Footing Plan Tie Beams Plan Pile Foundation Piles are structural member that are made of steel, concrete, or timber. They are used to build pile foundations, which are deep. When we Use Pile Foundations: Inadequate Bearing Capacity of Shallow Foundations. To Prevent Uplift Forces. To Reduce Excessive Settlement which cost more than shallow foundations.
