Abstract

Currently, because field-ready approaches are not available, individual wood members used in light-frame construction are typically replaced when fire reduces the total dimension of a member by approximately 1/4 inch or more in depth. Accordingly, the objective of this study is to provide a more quantitative approach for assessing serviceability of such members charred near this threshold but otherwise expected to remain in service. The following three materials are addressed: 1.9E laminated veneer lumber, Douglas-fir 2250f-1.9E machine stress rated lumber, and 1.7E ...
