Reassessment of Grading Criteria with Respect to the Flexural Properties of Douglas-fir Crossarms

Creator:: Anderson, Christopher H.
Abstract:: Wood plays a key role in modern electrical infrastructure; crossarms and power poles utilize the high strength to weight ratio, availability and low cost of wood to facilitate the access of power to millions of Americans. However, wood presents a variety of challenges as a material. In structural applications, one...

Toxicity of Fungal Pigments from Chlorociboria spp. and Scytalidium spp.

Creator:: Almurshidi, Badria H.
Abstract:: Commercial methodologies for producing fungal pigments are of worldwide interest due to the desire to move away from synthetic dyes. Chlorociboria species and Scytalidium species have been reported to produce sufficient yields of pigments for commercial production and have attracted special attention because of their use in spalted wood applications....

Development of a test method for assessing water repellency and derived physical stability of preservative systems for railroad ties

Creator:: Beck, H. Greeley
Abstract:: Resistance to moisture uptake is an important attribute of some wood preservatives and can help reduce moisture cycling that leads to the development of deep checks. While the potential for preservative treatments to help improve wood/moisture interactions is acknowledged, there are no tests that specifically evaluate this performance parameter. Checking...

Performance of partially and fully anchored wood-frame shear walls under earthquake loads

Creator:: Seaders, Peter, Miller, Thomas H., and Gupta, Rakesh
Abstract:: The objectives of this study were to evaluate the performance of wood-frame shear walls under monotonic, cyclic, and earthquake loads by: 1) comparing performance under each loading protocol; 2) evaluating effects of anchorage; and 3) eval-uating performance qualitatively and quantitatively with respect to code-deﬁned performance measures. Tests were conducted on...

Gravity and Wind Load Path Analysis of a Light-Frame and a Traditional Timber Frame Building

Creator:: Malone, Brian P., Miller, Thomas H., and Gupta, Rakesh
Abstract:: The objective of this study was to compare structural load path and system behavior of a light-frame (LF) and a timber frame (TF) structure. This load path analysis is part of a broader research effort that compares LF to TF residential structures. Structural analysis software was used to create a...

Effects of Roof Pitch and Gypsum Ceilings on the Behavior of Wood Roof Diaphragms

Creator:: Kirkham, William J., Gupta, Rakesh, and Miller, Thomas H.
Abstract:: Ten full-size (3.7×4.9m) plywood roof diaphragms were constructed using metal-plate-connected (MPC) common and hip wood trusses or joists, typical of single-family dwelling (SFD) construction. The specimens included three gable roof slopes of 33, 67, and 100%, a hip roof of 33% slope, and a flat roof, with a horizontal bottom...

Practical Analysis for Horizontal Diaphragm Design of Wood-Frame Single-Family Dwellings

Creator:: Kirkham, William J., Miller, Thomas H., and Gupta, Rakesh
Abstract:: Seismic design of wood-frame single-family dwellings’ (WFSFD) lateral force–resisting systems requires determination of the stiffness of horizontal diaphragms and shearwalls. During design, sizes and locations of shearwall openings are often changed, altering shearwall stiffness and loads and requiring a significant redesign effort. Rigid and tributary area method analyses are examined...

Do Douglas-fir branches and roots have juvenile wood?

Creator:: Peterson, M. G., Dietterich, H. R., and Lachenbruch, Barbara
Abstract:: We sampled boles, branches, and roots of four Douglas-fir (Pseudotsuga menziesii var. menziesii) trees to learn a) whether branches and roots have a zone of juvenile wood, defined as a zone with progressive changes in wood density and/or tracheid length from the pith outward at successively greater cambial ages, and...

A procedure for rapid visual screening for seismic safety of wood-frame dwellings with plan irregularity

Creator:: Lucksiri, Kraisorn, Miller, Thomas H., Gupta, Rakesh, Pei, Shiling, and van de Lindt, John W.
Abstract:: This paper highlights the development of a rapid visual screening (RVS) tool to quickly identify, inventory, and rank residential buildings that are potentially seismically hazardous, focusing on single-family, wood-frame dwellings with plan irregularity. The SAPWood software was used to perform a series of nonlinear time-history analyses for 480 representative models,...
