PART IFOUNDATIONS – INTRODUCTORY CONCEPTS M. Zoghi, Ph.D., P.E. Geotechnical Design Fall 2008
OUTLINE • Introduction • Types of Foundation • Design Criteria • Bearing Capacity • GWT http://www.eng.fsu.edu/~tawfiq/ceg4111/ShallowFoundation.html
I. Introduction • In general – “Foundation: that which supports something.” • Athletic Foundation – supports the school’s sports program. • Structural Foundation – that which supports a structure. • Soil-Structure Interaction
II. Types of Foundation • Shallow Foundations • Spread footings • Combined footings • Mat foundations • Deep Foundations • Pile foundations • Drilled piers
III. Design Criteria • Settlement • Bearing Capacity
Failure Mechanism General Shear Failure I. Elastic Zone; II. Radial Shear Zones; III. Rankine Passive Zones
Terzaghi’s Bearing Capacity Equations qult = Cohesion Term + Surcharge Term + Width Term
