Preset Configurations

Presets provide sensible defaults for common beam scenarios, reducing the number of required input parameters.

Quick Reference

Preset	Type	Description
genericBeam	Special	Flexible configuration with minimal defaults
genericFlitchBeam	Special	Steel-reinforced timber beam
floorJoist	Joist	Repeating floor members (16" o.c., top braced)
ceilingJoist	Joist	Ceiling framing member
deckJoist	Joist	Exterior deck joist (wet service)
rafter	Joist	Inclined roof member
floorGirder	Beam	Multi-ply beam supporting floor joists
floorHeader	Beam	Header over floor openings
roofGirder	Beam	Ridge beam supporting rafters
roofHeader	Beam	Header in roof framing
deckBeam	Beam	Deck beam (wet service)
comboBeam	Beam	Combined floor and roof loading
hipValley	Special	Hip or valley rafter geometry

Preset Categories

Joists

Repeating members installed at regular spacing. Includes floor joists, ceiling joists, deck joists, and rafters.

Beams

Girders and headers supporting other members. Includes floor/roof girders, headers, deck beams, and combination beams.

Special

Unique configurations including generic beam, flitch plates, and hip/valley geometry.

Overriding Defaults

All preset defaults can be overridden by explicitly providing values:

Code
 
{
  "preset": "floorJoist",
  "attributes": {
    "L_X": 14,
    "member": "2x10 D.Fir-L No. 1",
    "spacing": 12,
    "Delta_Span_ST": 480,
    "supports": [["Pinned", 0, 3.5], ["Pinned", 14, 3.5]],
    "loadsDist": [["Floor Load", 0, "L", "spacing", "TW_s", {"D": [10], "L": [40]}]]
  }
}
