  2. Shallow Foundations • Shallow Foundations versus Deep Foundations

  3. Shallow Foundations • Usually the more economical option • As a general rule, consider deep foundations only when shallow foundations do not give satisfactory design • Types of Shallow foundations • Spread footings (square, circular, rectangular) • Combined Footings • Continuous Footings • Mat or Raft Foundations

  4. Combined/Strap Footing

  5. Construction Methods • Excavation; Backhoe followed by handwork • Neat footing-no formwork used • Formed footing

  6. Mat (or Raft) Foundation

  7. Computation of Bearing Pressure • Bearing Pressure • Gross Bearing Pressure (q) • Net Bearing Pressure(q´) • Bearing Capacity • Ultimate Bearing Capacity (qult) • Allowable Bearing Capacity (qa)

  8. Computation of Bearing Pressure • Column Load (Ex 5.1) • Wall Load (Ex 5.2)

  9. Net Bearing Pressure • Net Bearing Pressure (q´) • Floating Foundation • When q´ = 0 • Example: Student Center Building at MIT Estimated without floatation settlement = 1.0ft and settlement with partial floatation was 2-3 inches
