Immediate Foundation Settlement Calculator
Elastic half-space settlement qB(1−ν²) I/E, caller geometry influence factor. Caller independently establishes units, regime, calibration and applicability; this does not establish design-code compliance, authenticity, operational safety, treatment efficacy or a validated forecast.
Description
Immediate elastic settlement depends on pressure, footing width and a soil stiffness model.
Immediate elastic settlement depends on pressure, footing width and a soil stiffness model.1
Its shape factor and soil assumptions must be justified independently. Use this tool to calculate immediate Foundation Settlement from the supplied measurements and assumptions.
When to use Immediate Foundation Settlement Calculator
Use this tool to calculate immediate Foundation Settlement from the supplied measurements and assumptions. Establish the SI units or caller unit basis, load signs, measurement interval, model conditions and independently chosen coefficients or references.
How to use Immediate Foundation Settlement Calculator and understand its results
- Establish the SI units or caller unit basis, load signs, measurement interval, model conditions and independently chosen coefficients or references.
- Enter netPressurePa, footingWidthM, soilYoungPa, poisson, callerShapeFactor, using the field meanings and rules below, then run the tool.
- Read elasticImmediateSettlementM. Interpret the fields using their units, signs and evidence conventions below.
- If input validation fails, correct the reported field and run again. Before applying the result, check reference scope, model assumptions and any missing evidence or placeholder values.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| netPressurePa | Net pressure pa | number | Required |
| footingWidthM | Footing width m | number | Required |
| soilYoungPa | Soil young pa | number | Required |
| poisson | Poisson | number | Required |
| callerShapeFactor | Caller shape factor | number | Required |
Enter nonnegative net pressure in Pa, positive footing width in m, soil modulus in Pa and shape factor, with Poisson ratio in [0,0.5). Return pressure×width×(1−poisson²)×shape/modulus in m. The value 0.5 fails; no consolidation, layered soil or shape-factor estimation is included.
settlementM=netPressurePa×widthM×(1−ν²)×shapeFactor/soilYoungPa Use the exact units, boundary rules, ordering and missing-evidence conventions above.
| Output field | Meaning | Value type |
|---|---|---|
| elasticImmediateSettlementM | Elastic Immediate Settlement M; follow the units, sign, ordering and evidence convention stated above | number |

}Limitations and assumptions
Its shape factor and soil assumptions must be justified independently. Interpretation depends on the units, sampling scope and exact model described above.
All listed fields require explicit values. Unexpected fields, incorrect types, nonfinite numbers and sparse evidence arrays fail validation; the specific bounds and alignment requirements are stated above. Extremely large inputs or outputs can also be rejected. An input error is distinct from a successful result reporting false, no matches or missing evidence.
