Eccentric Weld Group Shear Calculator
Elastic eccentric shear over independently measured discrete weld throat patches, direct plus centroid moment, not continuous-weld stress concentration or 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
An eccentric weld-group model combines direct shear with moment-related traction.
An eccentric weld-group model combines direct shear with moment-related traction.1
Its area distribution and chosen point-patch representation determine the computed stresses. Use this tool to calculate eccentric Weld Group Shear from the supplied measurements and assumptions.
When to use Eccentric Weld Group Shear Calculator
Use this tool to calculate eccentric Weld Group Shear 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 Eccentric Weld Group Shear 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 observedWeldPatchAreasM2, observedWeldPatchCentersXyM, directForceXyN, eccentricMomentNm, using the field meanings and rules below, then run the tool.
- Read patchShearTractionsPa, maximumPatchTractionPa. 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 |
|---|---|---|---|
| observedWeldPatchAreasM2 | Observed weld patch areas m2 | list of number | Required |
| observedWeldPatchCentersXyM | Observed weld patch centers xy m | list of list of number | Required |
| directForceXyN | Direct force xy n | list of number | Required |
| eccentricMomentNm | Eccentric moment nm | number | Required |
Enter positive patch areas, aligned planar patch centers, a two-component direct force and signed moment. Find area-weighted centroid and J=Σarea×squaredDistance; J must be positive. Add direct force/totalArea to the tangential moment traction at each patch and return components and maximum norm in Pa. Patches use center contributions only, without each patch's intrinsic polar inertia or capacity checking.
traction_i=[Fx/A−M(y_i−cy)/J,Fy/A+M(x_i−cx)/J]; J=ΣA_i×r_i² Use the exact units, boundary rules, ordering and missing-evidence conventions above.
| Output field | Meaning | Value type |
|---|---|---|
| patchShearTractionsPa | Patch Shear Tractions Pa; follow the units, sign, ordering and evidence convention stated above | list of list of number |
| maximumPatchTractionPa | Maximum Patch Traction Pa; follow the units, sign, ordering and evidence convention stated above | number |

}Limitations and assumptions
Its area distribution and chosen point-patch representation determine the computed stresses. 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.
