This application calculates settlement of a footing placed on a cohesionless material (sand) using the Schmertmann method (Schmertmann, 1970, Schmertmann et al, 1978).

### Input

• Units:
• kPa: This gives stress in kPa (kilopascals), length in m (meters) and settlement in cm (centimeters)
• ksf: This gives stress in ksf (1000 pounds per square foot), length in feet and settlement in inches
• tsf: This gives stress in tsf (tons per square foot), length in feet and settlement in inches
• Layers:
• Thickness: This is the thickness of each layer starting from the surface, not from the bottom of the footing.
• qc: This is the cone tip bearing resistance from a Cone Penetration Test.
• Es: This is the one-dimensional modulus used in the settlement calculation. You may choose to enter this directly. Otherwise, it will be calculated from qc (see below)
• γmoist: Unit weight of soil above the water table.
• γsat: Unit weight of soil above below the water table (saturated).
• Options:
• Use Es: By default, you must enter qc for each layer and the program converts to the one-dimensional modulus Es (as shown here). By choosing this option, you may enter Es directly.
• Use modified Schmertmann (1978): In Schmertmann et al (1978), more accurate equations were derived for the strain profile and for converting qc to Es
• Subdivide layers: The accuracy of results improves as more layers are entered. Select this option and the program will automatically divide up your soil layers to ensure a good discretization
