Facade Roof Bracket Connection Package

Calculates source-bound facade or roof bracket connection metrics from a deterministic SSC-14 task-owned source pack. The template combines wind tributary load, bracket reaction, anchor combined utilization, carbon-equivalent material screening, and overall pass scoring.

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

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 source-pack values given for the SSC-14 bracket connection package
medium:
All source-pack values given for the SSC-14 bracket connection package
hard:
All source-pack values given for the SSC-14 bracket connection package
