Steel Set Support Capacity Calculator
Audit actual steel-set load inventory versus independently certified same-installation capacities, unavailable capacities separate; no generic material-based design or support safety certification. Caller independently verifies units, applicability and matching conditions; no operational recipe, safety certification, causal efficacy or legal/resource classification is inferred.
Description
Installed steel-set loads and matched certified capacities describe a particular support inventory.
Installed steel-set loads and matched certified capacities describe a particular support inventory.1
Unknown capacities need separate reporting from measured deficits.
When to use Steel Set Support Capacity Calculator
Use this tool to calculate or review the supplied observations under the stated rules. Match completed survey or ledger observations by block, segment or stage and confirm their units and boundaries.
How to use Steel Set Support Capacity Calculator and understand its results
- Match completed survey or ledger observations by block, segment or stage and confirm their units and boundaries.
- Enter observedSteelSetLoadsKn, callerVerifiedMatchedSteelSetCapacitiesKn, knownSteelSetCapacityFlags, using the field meanings and rules below, then run the tool.
- Read signedMargins, knownDeficitIndices, unknownCapacityIndices. Inspect nested result fields where present, and review unknown records separately from known matches.
- Correct any reported input issue and run again. Before using a successful result, check the stated units, signs, reference scope and observation coverage.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| observedSteelSetLoadsKn | Observed steel set loads kn | list of number | Required |
| callerVerifiedMatchedSteelSetCapacitiesKn | Caller verified matched steel set capacities kn | list of number | Required |
| knownSteelSetCapacityFlags | Known steel set capacity flags; binary 1 means the matched observation is known, 0 means unknown | list of number | Required |
Use aligned nonnegative loads and capacities with binary capacity-known flags. Known margin=capacity−load; unknown rows receive zero placeholders. Return known strictly negative margin indices and separate unknown capacity indices. Boundary equality is not a deficit.
margin_i=known_i?(capacity_i−load_i):0 Use the matching field units and the exact boundary, ordering and reference rules above.
| Output field | Meaning | Value type |
|---|---|---|
| signedMargins | Signed margins; preserve the subtraction order and sign defined in the mechanics | list of number |
| knownDeficitIndices | Known deficit indices; zero-based positions in the relevant supplied record or adjacent-pair list | list of number |
| unknownCapacityIndices | Unknown capacity indices; zero-based positions in the relevant supplied record or adjacent-pair list; unresolved records kept separate from known results | list of number |

}Limitations and assumptions
Units, ledger boundaries, survey interpretation and model applicability must be independently established. These summaries do not assign reserve/resource classifications or establish support adequacy, ventilation safety or an operating setting.
Missing required fields, unknown fields, wrong types and violated rules return input issues. Numeric values and outputs must be finite. Lists and matrices must be dense, without missing cells. Numeric lists allow at most 10000 entries; ordinary string lists allow at most 128 strings of 128 UTF-16 units each; numeric matrices allow at most 128 rows and 128 columns, subject to narrower requirements above.

For a complementary comparison, use Rock Bolt Tension Calculator: Calibrated axial stiffness and measured strain can infer bolt tension above an independently observed preload.
