A column assembly preferably includes a tube member having a wall that defines an interior volume. The column assembly is preferably operable to convert external, axial compressive forces applied to the column assembly into at least tangential stresses within the wall of the tube member. In one embodiment, an external compressive force causes increased pressurization of a filler material located within the volume of the tube member. The pressurized filler material produces tangential, tensile stresses within the wall of the tube member rather than axial compressive forces within the wall of the tube member. In some embodiments, a reinforcing, tension member, e.g., a wire rope, may be helically wound around the outer surface of the tube member along at least a portion of its longitudinal length.
