A residential building is to be located at a site with a representative soil stratum as shown in the figure. The loads from all columns and size and spacing of the columns are shown in the figure. All dimensions are in meters if not expressed. All loads are in kN if not mentioned. Design the suitable foundation system to safely transmit the loads. The total settlement should not exceed 25 mm and the differential settlement should not exceed 10 mm. The soil test data on consolidation for the soil collected from the center of clay layer is presented in table 1. Other soil test data gave us the following soil parameters: Poisson's ratio Young's Modulus of Elasticity Effective friction angle Undrained shear strength Geotechnical Parameter Dry unit weight Saturated unit weight Specific Gravity Moisture Content Table 1 Vertical stress (kPa) Void Ratio Tasks: 1. 2. 3. 4. 50 0.945 SP Material 0.3 7 MPa 32⁰ 16.5 kN/m³ 19.5 kN/m³ 100 0.920 200 0.889 CH material 0.4 800 kPa 100 kPa 18.5 kN/m³ 2.69 42% 400 0.542 800 0.375 Design isolated footing and check for settlement. Present hand calculation for at least one footing. Check settlement for mat foundation. Size of the mat is already known.
