Deep Beam Shear Calculator
Caller independently resolved diagonal compression strut idealization V/(sinθ A), angle0<θ<π/2, not sectional shallow-beam shear capacity. 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
A diagonal strut idealization relates support shear to compression force and area.
A diagonal strut idealization relates support shear to compression force and area.1
Its angle and effective area require independent model selection. Use Deep Beam Shear Calculator to evaluate the supplied inputs under the specific model below.
When to use Deep Beam Shear Calculator
Use Deep Beam Shear Calculator to evaluate the supplied inputs under the specific model below. Establish the units, measurement scope and applicable model or recipe assumptions before entering values.
How to use Deep Beam Shear Calculator and understand its results
- Establish the units, measurement scope and applicable model or recipe assumptions before entering values.
- Enter Deep beam support shear n, Caller compression strut angle rad, Caller independent compression strut area m2 using the field table and validation rules below, then run the tool.
- Read Ideal deep beam diagonal compression pa and interpret units, signs, ordering and placeholders as explained below.
- If the tool reports an input error, correct that field and rerun. A successful false result, empty match list or unknown-evidence placeholder has the specific meaning described here; check the limitations before applying the result.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| deepBeamSupportShearN | Deep beam support shear n | number | Required; constraints below |
| callerCompressionStrutAngleRad | Caller compression strut angle rad | number | Required; constraints below |
| callerIndependentCompressionStrutAreaM2 | Caller independent compression strut area m2 | number | Required; constraints below |
Enter nonnegative support shear V in N, a strut angle θ strictly between 0 and π/2 radians and a positive independently established strut area A in m². Divide shear by sin(θ) to obtain the ideal strut force, then divide by area for compression in Pa. This does not size reinforcement or check a complete strut-and-tie system.
compressionPa = V/(sin(θ)×A) Field order, units and branch conditions follow the implementation explanation above.
| Output field | Meaning | Value type |
|---|---|---|
| idealDeepBeamDiagonalCompressionPa | Ideal deep beam diagonal compression pa | number |

}Limitations and assumptions
Its angle and effective area require independent model selection. Apply the exact scope and assumptions described above.
All listed fields require explicit values. Unexpected fields, incorrect types, nonfinite numbers and sparse arrays fail validation. Domain-specific bounds, alignments and supported tokens are stated above; extremely large inputs or outputs can also be rejected. These errors differ from successful results such as false, no matches or unknown evidence.
