Abstract

An assessment was made of the effect of preservative treatments on bending strength and stiffness of full-sized marine piles and small specimens derived from them and on the compression strength of pile sections. Preservative-treated Southern pine and Douglas-fir piles were generally lower in strength than untreated piles. Dual treatments of ACA plus creosote and CCA plus creosote reduced strength more than single treatments with these preservatives. Stiffness and strength in compression were not affected by preservative treatment. Statistical associations between MOE and MOR values of small specimens and full-sized piles in bending were extremely small.
