What Bearing Capacity Means in Preliminary Design
Wanneer dit van toepassing is
Use this guide for first-pass footing discussions when you need transparent ultimate-pressure math before site-specific geotechnical design.
Te gebruiken tool
Terzaghi shallow strip ultimate bearing — teaching estimate, not code output.
Bearing Capacity Calculator openen →Stappen
- 1Gather the assumed soil strength parameters, footing width, and embedment depth.
- 2Compute overburden and the Terzaghi-style ultimate bearing estimate.
- 3Apply an explicit factor of safety if you want a quick allowable-pressure screening value.
- 4Document everything the estimate does not include, such as settlement and groundwater effects.
- 5Move to geotechnical investigation and code-based design as soon as the concept becomes project-relevant.
Voorbeelden
- Comparing preliminary footing concepts before geotechnical recommendations are finalized.
- Explaining why width and friction angle assumptions change results quickly.
Vermijd dit
- Treating a classical bearing formula as a full geotechnical design package.
- Ignoring groundwater and settlement implications.
- Using an assumed phi or cohesion value without stating the source.

Veelgestelde vragen
Does this include settlement?
No. Settlement and serviceability checks are outside the scope of this preliminary pressure estimate.
Can I use this as a code-compliant footing design?
No. It is a transparent first-pass calculation, not a code-compliant foundation design workflow.
