Glue Laminated Timber Sizing

Overview

Engineering reference data for Glue Laminated Timber Sizing in material science and properties.

Key Formulas

Stress

$\sigma = \frac{F}{A}$

Force per unit area.

Strain

$\varepsilon = \frac{\Delta L}{L_0}$

Change in length per original length.

Hooke's Law

$\sigma = E \varepsilon$

Stress proportional to strain in elastic region.

Thermal Expansion

$\Delta L = \alpha L_0 \Delta T$

Length change due to temperature.

Variables

Symbol	Description	Unit
$\sigma$	Stress	Pa
$\varepsilon$	Strain	—
$E$	Young's modulus	Pa
$\alpha$	Thermal expansion coefficient	1/°C
$\Delta T$	Temperature change	°C

Glulam Timber Dimensions

Glulam timber beams are available in standard nominal widths, which correspond to specific actual dimensions. The table below provides these measurements for common glulam sizes.

Note: 1 inch = 25.4 mm
