Timber Design Module

A powerful tool for designing or checking continuous beams and columns

Module Description

Design or check any continuous beam or column using the latest building codes (NDS, IBC, ASCE) in just a couple of minutes.

Powered by the STRAAD finite element engine, Timber Design can analyze any beam or column, regardless of support and loading conditions.

Timber Design uses the latest NDS design code to design multi-span beams or columns for bi-axial bending, axial loads, axial-bending interaction, torsion, shear, support bearing and deflections.

Technical Specifications

  • Powered by STRAAD finite‑element analysis, giving engineers the freedom to model nearly any support or loading condition — even elastic‑foundation beams like grade beams.
  • Analyzes and designs continuous beams and columns up to 15 spans/stories, including multi‑member beams for long runs or spliced lumber.
  • Handles rafters with or without ridge‑beam support, making it ideal for real‑world roof framing.
  • Fully aligned with NDS 2018, covering support bearing, axial tension/compression, bi‑axial bending, shear, torsion, and deflection checks.
  • Features live‑load patterning, live‑load reduction, and automatic ASCE/IBC load combinations, reducing manual setup time.
  • Designs incised members and allows independent top and bottom flange bracing configurations.
  • Computes and designs for shear deformation in I‑joists for more accurate behavior.
  • Wizard‑driven input keeps the workflow fast, clean, and intuitive.
  • Produces polished RTF reports and printable graphics — geometry, loading, shear, moment, torsion, and deflection diagrams — for single cases or full envelopes.
  • Supports US and metric units, including architectural notation, with a simple, engineer‑friendly interface.
