Single footing data
Parameters that the software uses for a single footing settlements calculation are:
•Footing width: The smallest dimension of the footing in meters.
•Footing length: The largest dimension of the footing in meters.
•Footing load: This is the total pressure that the footing transfers to the ground in kPa. Please have in mind that this value should include the weight of the footing.
•Embedment depth *: Measured from the free surface, this is the depth that the software will use to determine the initial effective stress which will be abstracted from the footing's total pressure (in meters).
•Water table *: Measured from free surface, this is the depth that ground water table exists.
•Limit calculation to 20% *: According to DIN 4019 and Eurocode 7 (Clause 6.6.2 (6)), settlements calculation can be carried out until the effective vertical stress due to footing pressure becomes less than 20% of the effective overburden pressure. When checked the software uses the above rule.
•Rigid footing *: If checked then calculations are contacted for a rigid footing which practically means that settlements below the footing will be uniform.
•Perform bearing calc.: When checked the software will perform a parametric analysis of soil bearing capacity according to the procedure described in DIN 4017 for drained conditions.
* These parameters will also be used in the parametric analysis.
Parameters regarding soil layers are:
•Bottom z: This is the absolute bottom of the soil layer, measured from the free surface (in meters).
•Thickness H: This value is automatically calculated from the software and it is the thickness of the soil layer (in meters).
•Elast. Es: This is the value for the modulus of elasticity in MPa.
•Gamma: This is the bulk unit weight of the soil layer (in kN/m³).
•Friction angle: This is the internal friction angle of the soil layer in degrees.
•Cohesion: This is the cohesion of the soil layer in kPa.
The soil layers data are also used from the parametric analysis.
