Lam I-Joists: A New Structural Building Product from Small-Diameter, Fire-Prone Timber

摘要

Over the past 50 years, forest biomass has increased as a result of normal growth and the suppression of forest fire, which contributes to high forest fuel loads. In the absence of thinning, whether manually or by natural means, many of these forests have become prone to catastrophic forest fire, insect infestation, and disease. Moreover, the risk of loss of property and life through fire has increased dramatically with the expansion of the wildland-urban interface. The amount of residual hazardous fuel in these forests thus needs to be reduced.
