Residential Beam Load Tables
load-tableReference load tables for common beam types used in residential construction, including LVL, glulam, and steel W-shapes. Covers allowable uniform loads and maximum spans for standard configurations.
LVL Beam Allowable Spans (40/10 psf Floor Load)
Source: Based on Weyerhaeuser Microllam LVL design values; Fb = 2,900 psi, E = 2.0 × 10⁶ psi| Configuration | Tributary Width 4' | Tributary Width 6' | Tributary Width 8' | Tributary Width 10' |
|---|---|---|---|---|
Steel W-Shape Allowable Uniform Load (kips)
Source: AISC Steel Construction Manual, 15th Ed. — ASTM A992 Grade 50| Shape | Weight (lb/ft) | Span 10' | Span 14' | Span 18' | Span 22' |
|---|---|---|---|---|---|
Applicable Codes & Standards
- • IRC R502.5 — Bearing
- • IRC R606.9 — Steel beam bearing on masonry
- • IBC 1604.3 — Deflection limits
- • AISC 360 — Specification for Structural Steel Buildings
- • NDS — National Design Specification for Wood Construction
These tables provide general reference values for preliminary beam selection. Actual beam sizing must account for specific loading conditions, bearing details, deflection criteria, and local code requirements. Consult a structural engineer for final beam specification.
