Test Setup: Five each 8″ diameter x 4 ft. long timber piles with fiberglass reinforced jackets, grout and carbon ﬁber grid. To simulate deterioration, ﬁve of the piles had a hourglass–shaped varying depth cut into them at mid-span. There were two more piles that were used as baseline controls, one specimen was a plain timber pile with no repairs and the other had a hourglass–shaped cut into them at mid-span with no repairs. The repairs were installed 8” above and below the hourglass area. The objective was to evaluate the behavior of the mid section repair of a deteriorated timber pile and quantify the additional axial compressive strength from the repairs vs. the baseline control specimens.
Results: The results of showed that the repair will increase the axial capacity of the damaged pile from 198% to 483%. The ratios between the peak loads of repaired piles and undamaged pile varied from 1.03 to 1.22, which means that the repair not only restores the original axial capacity of the pile but also enhances it by 3% to 22%.
