Description

Incomplete

Design needs geometry, loading, and at least one material family before candidate sizing can run.

Include beam self-weight — all spans Included in Dead Load

Tributary width is entered on each load. The graphic shows entered loads for all spans. Press Calc Now (Ctrl+Enter) when ready to run engineering.

Size constraints

Max depth / height in.

Max width in.

Optional. Depth = dressed member depth; width = total built-up width (b × plies). Beams: 1–4 ply built-up. Joists/Rafters: single ply.

Check a material group to include it. Dimensional: select one or more grades per species (Ctrl/Cmd-click). Steel: expand the group, then check shape families. Partial group selections show a dash (−) in the checkbox. Expand All / Collapse All applies to Dimensional, Engineered, Glulam, and Steel. Only selected materials appear in Design results. Default: SYP No. 1, Microllam® LVL, W-shapes. Steel uses AISC ASD.

C_D from ASD load duration (NDS Table 3.1.2).

C_t = 1.0 and C_i = 1.0 assumed. C_r = 1.15 when Repetitive Member is checked (dimensional F_b). C_M applies to dimensional and glulam when Exterior Exposure is on.

ℓ_e = K × unbraced height (K = 1.0 pin-pin assumed). C_p governs by the weaker buckling axis. Limit ℓ_e/d ≤ 50 (NDS 3.7.1.5).
