...Robert Lepage; Samuel V. Glass; Paul Y. de la Bastide; Phalguni Mukhopadhyaya The established methods for determining the effects of ultrastructural changes in structural wood members rely upon traditional, possibly outmoded, testing paradigms. These methods usually involve destructive testing...

...Paul Frederik Laleicke; David C. Tilotta; Phil H. Mitchell; Matthew Byington Wood moisture meters are needed for a variety of purposes, including home inspections, assessment of water damage, evaluation of firewood, do-it-yourself (DIY) projects, and many more. With an increasing number of flood...

...K. Walker; T. H. Miller; R. Gupta; A. Shariati; T. Schumacher Inspection techniques for wood structures are typically based on visual observations of degradation, and often limited to localized observable surface damage on the structure, rather than holistic non-destructive evaluations. Hidden...

...) to apply this model to data on wood-failure percentages from block-shear tests on structural wood adhesives. We treat percentage responses measured in 5-point intervals as having arisen from observing 20 independent binary responses on different parts of the observed wood blocks. The overdispersion...

...Robert J. Leichti; Karl Kleemann; Thomas H. Miller The important role of boundary conditions in tests of compression members was evaluated when determining the instability loads of asymmetric and nonprismatic compression webs for wood trusses. The compression webs were created by nailing a side...

...SL Zelinka This paper evaluates the effect that uncertainties in measurements of time, weight, and surface area have on the determination of the corrosion rate of metal fasteners in contact with wood. Three different types of nails were driven into alkaline copper quaternary (ACQ)-treated wood...

... under test conditions that included the presence of moisture and temperature fluctuations, and the effect of wood preservatives. The objectives of this study were: 1) to determine if the current test methods used to assess durability of wood-wood bonds for exterior use (ANSI/AITC and ASTM D 2559...

...T Ohtani; K Kamasaki The wear properties for wood were examined using 2-body and 3-body abrasion tests. The testing methodologies were designed so that the results from the two methods could be compared. The results showed that the 3-body abrasive wear rate for the axial, radial, and tangential...

...Y Hong; L Muszyński; R A Lopez-Anido The design, modeling, and calibration procedure of a prototype mechanical clamping device for fabricating wood and fiber-reinforced polymer (FRP) composite laminated billets for ASTM D 2559 delamination tests and shear block tests is presented.

...M Patton-Mallory; FW Smith; PJ Pellicane A three-dimensional (3-D) finite-element model was developed and verified which is capable of predicting the failure mode and load-deformation (P - Δ) behavior of a single bolted connection in wood. The 3-D geometry of the model is complemented...

...M Patton-Mallory; PJ Pellicane; FW Smith Two hundred forty-three experiments were conducted on bolted wood connections having a variety of aspect ratios (length of bolt in member/bolt diameter) and end distances with loading applied in tension and compression.
