Wood shear walls are the main lateral force-resisting system for wood-frame construction. Water intrusion and subsequent decay around connections can significantly impact shear wall behavior, but these problems are seldom studied. In this study, effects of water intrusion and fungal attack on shear wall capacity were examined using small-scale (610-...
Wood I-joists are often left uncovered and exposed to the weather during construction, allowing the oriented strandboard and laminated veneer lumber in these systems to be adversely affected by water absorption. Manufacturers typically specify that these materials be protected from wetting, but this can be difficult in wetter climates. There...
The Oregon Coast Range contains large acreages of nonstocked
high site land. With the increasing demand for wood products, more
attention is being given to the problems of reforesting these lands.
This study develops financial guidelines to the reforestation
of nonstocked high site lands. A number of possible owner constraints...
Some of the world's most productive timberland lies on the slopes of the coastal range in Oregon and Washington. More than one-half of the commercial forest land in that area is estimated as high site quality for Douglas-fir, with a site index of 140 or better. But much of this...
