An article and a process are provided for reducing the shear stress on an
interface of a structural member in intimate contact with a compressive
load. The article is in the form of a wedge that is forcibly placed
against the sidewall of one end or both ends of the structural member.
The wedge may take the form of a ring that can be placed on the inside or
outside surface of a hollow cylindrical structural member. The process of
forcibly placing a wedge against the sidewall at one or both ends of the
structural member produces a transverse compressive stress upon the
sidewall. The transverse compressive stress upon the sidewall attenuates
the tendency of said sidewall to deflect when the structural member is
subjected to a compressive load. A reduction in the deflection of the
sidewall reduces the shear stress generated proximal to the interface of
the structural member in intimate contact with a compressive load and
increases the structural member load bearing capacity.
