Serviceability of Douglas-fir marine piles and control of their deterioration

Creator:: Helsing, Guy Gustav
Abstract:: In an exploratory survey of the serviceability of wood in the marine environment in the Pacific Northwest, pressure-creosoted piling with tops protected from wetting by the superstructure provided 40 and more years of service and showed little or no indication of deterioration. The service life of these piling is still...

Establishment of Poria carbonica in wood and colonization by basidiomycetes of Douglas-fir utility poles during air seasoning

Creator:: Przybylowicz, Paul
Abstract:: Influence of temperature and wood moisture content on spore germination and colonization of Douglas-fir (Pseudotsuga jnenziesii) heartwood by Poria carbonica basidiospores and chlamydospores was studied. Both spore types germinated and colonized wood at moisture contents above the fiber saturation point, but not below. Germination and wood colonization occurred at 22°C...

The development and use of breaking radius and impact bending tests for measuring wood strength loss caused by basidiomycetes isolated from air-seasoning Douglas-fir

Creator:: Sexton, Camille Marie
Abstract:: Douglas-fir utility poles are routinely air seasoned before treatment with chemical preservatives. Basidiomycetous fungi invade these poles and may cause strength loss during air seasoning or later if treatment temperatures are insufficient to kill the decay fungi. The purpose of this study was to develop a rapid test to asses...

Potential for Using Boron Compounds with Differing Water Solubilities in Pastes for Remedial Treatment of Utility Poles

Creator:: Uysal, Selim
Abstract:: Boron and boron compounds have been long used for pressure treatment, dip-diffusion, and remedial treatments of wood because of their proven efficacy against fungi and insects. These materials are especially attractive because their high water solubility promotes deeper penetration into wood. Other useful properties of boron include its neutral pH,...

Dynamic modeling of thermal treatment of timber poles

Creator:: Sahle-Demessie, Endalkachew
Abstract:: The temperature-time-location relationships during steam conditioning and pressure treatment of timber poles have been studied and mathematical models that take into account both the thermal properties of the poles and the parameters of the treatment process have been developed. Although much work has been previously done in this area, the...

Establishing a through-boring pattern and method of test for utility poles

Creator:: Elkins, Lori A.
Abstract:: The goal of this study was to optimize a through-boring pattern that will provide adequate preservative penetration while minimizing the reduction in overall pole bending strength. Hole spacing was developed using longitudinal and transverse chemical penetration data from previous studies. Finite element analysis was used as a preliminary assessment tool...

Ground Improvement and Liquefaction Mitigation using Driven Timber Piles

Creator:: Gianella, Tygh N.
Abstract:: Seismically-induced liquefaction represents a major cause of damage to civil infrastructure and can result in significant damage following major earthquakes. Liquefaction can occur when earthquake ground motions raise pore-water pressures in loose, sandy soil, resulting in a substantial decrease of soil strength. Owing to the potential for instability following liquefaction,...
