In order to describe long term creep behavior of structural lumber in a natural
environment, a bending test with twenty Douglas-Fir beams subjected to a constant
load was set up in an open shed in the Forest Research Laboratory at Oregon State
University. Deflections of the beams were measured along...

As lumber producers are faced with a diminished and increasingly expensive raw
material, the need to maximize resource recovery will increase. Trim-ends (particularly
from waned boards) often contain some of the highest quality wood in any given log
and lack functionality only in length. This waste, traditionally chipped for pulp,...
The first objective of this research is to develop primal and dual models of firm
behavior that incorporate firms' conjectures of their market power positions. The second
is to empirically test for the presence of market power in eastern Oregon's stumpage and
lumber markets. Eastern Oregon was chosen since it...
Large inelastic strain occurs inside a piece of lumber during drying. The strain consists of several components such as elastic, plastic, creep, shrinkage and mechano-sorptive effect. The mechanical behavior of the whole board during drying is determined by the behavior of individual strain components and their interactions. Whereas limited investigations...
