Effects of preservative treatments on the axial load characteristics of nailed wood joints

Authors: Lapp, H.M., Otis, C. K. And J. R. Neetzel
Description: Nailed joints, fabricated from various combinations of nails and timbers provide the most common type of mechanical fastening for farm structures. Resistance to loading is affected by such nail characteristics as diameter, length, surface finish or coating and point design. Strength is also affected by wood properties such as density, direction of grain, whether hardwood or softwood, presence of defects and variations in moisture content. Many of these properties have been investigated by research organizations and results have been incorporated into various Timber Design Manuals and Handbooks (1, 2, 4, 5). Recommendations in these publications apply to lumber which has not been subjected to any type of preservative treatment prior to construction. Modern structures, and particularly farm buildings, frequently employ preservative treated lumber in the design to prevent or impede the ravages of wood decay and thus extend the life of structures. The nature of treatment is such that fibres of wood members are penetrated by preservative chemical which could affect joint strength characteristics. The objective of this paper is to report on the axial load characteristics of nailed joints in one species of wood (Ponderosa Pine) subjected to: (a) pressure treated pentachlorophenol, (b) pressure treated creosote,
