Bracket Load Calc

Calculates service vertical load, factored vertical load, factored lateral load, and resultant bracket action using explicit load effects and factors. The template is a reduced deterministic load calculation, not a full bracket capacity design.

with-tool: The model is given an executable Python calculator script.

How this task is generated

One template produces many comparable benchmark tasks while keeping the scoring contract fixed.

  1. 01

    Template

    The reusable contract shown on this page.

  2. 02

    Scenario

    An archetype and site context are sampled.

  3. 03

    Difficulty tier

    Inputs may be hidden at harder tiers.

  4. 04

    Task prompt

    The model responds with the declared outputs.

Parameters

Inputs the model receives, and the outputs it is scored on.

Inputs

6 inputs

Always given

Included directly in every task prompt.

Scored outputs

4 outputs

Service vertical load kn

service_vertical_load_kn

Service vertical bracket load

Scores if within ±3% of the reference value.

Factored vertical load kn

factored_vertical_load_kn

Factored vertical bracket load

Scores if within ±3% of the reference value.

Factored lateral load kn

factored_lateral_load_kn

Factored lateral bracket load

Scores if within ±3% of the reference value.

Factored resultant load kn

factored_resultant_load_kn

Factored resultant bracket load

Scores if within ±3% of the reference value.

Difficulty

Each template is sampled at three tiers. Harder tiers may hide inputs, forcing the model to infer them from the scenario description.

All inputs remain visible at every tier

For this template, difficulty scales through parameter and scenario ranges rather than hidden information.

easy:
All parameters given for a facade bracket
medium:
All parameters given across bracket types
hard:
All parameters given for equipment brackets
