Strength loss associated with steam conditioning and boron treatment of radiata pine framing

IRG/WP 3438

M J Collins, P Vinden

The combined effect of included defects and wood moisture content on the strength loss of second rotation radiata pine framing following conventional steam conditioning is investigated. The green Modulus of Elasticity (MOE) is reduced by approximately 13% after steaming. When dried after steaming, however, neither the MOE nor MOR is significantly different from unsteamed dried controls.
