THE EFFECT OF CONFINING PRESSURE ON THE COMPRESSION PARALLEL-TO-THE-GRAIN STRENGTH OF SMALL CLEAR WOOD SPECIMENS.
Abstract
Since wood foundation piles are normally used under conditions of confining lateral pressure from the soil in which they are imbedded, it has been suggested this pressure may have an effect upon the compression parallel-to-the-grain strength of the piles. Accordingly, a study was conducted to evaluate the effect of this pressure on the compression-parallel strength of small clear specimens of Douglas-fir and red oak. To simulate earth pressures, oil pressures of 50 and 100 pounds per square inch were used. No effect was found on the strength of the two species at either pressure. (Author)
