摘要
The longitudinally compressive and tensile proportionality limits and ultimate strengths of an elongated structural member are increased by applying to the member a longitudinally compressive load which is close to its maximum load. In order to prevent buckling of the member under such a load, the member is confined in an encasement which allows the member to yield longitudinally without bending. By applying to the member a longitudinally compressive load much greater than the member's original (i.e. untreated) ultimate compressive strength, both the ultimate strengths and the proportionality limits of the member are increased. In addition, application of a longitudinally compressive load close to or greater than the original ultimate compressive strength of the member also increases the straightness of the member and frees the member of residual stresses.
