Engineered F17 LVL Beams: Design Tables for 9.5 m Clear Spans with Deflection ≤ L/250

Category:

Description

Engineered F17 LVL beams manufactured from 100 % select-grade radiata pine deliver a characteristic bending strength of 70 MPa and modulus of elasticity of 13.8 GPa, enabling 9.5 m single-span residential floor joists at 300 mm centres while satisfying AS1720.3 deflection limits of L/250 under combined G + ψsQ loads.
