Abstract

A tension tie member is anchored between two spaced locations on a structure, such as a diagonal cable in a stayed girder bridge. The tie member is supported on the structure adjacent at least one anchor location by an annular bearing member encircling an outer protective casing of the tie member. The bearing member is positioned within an annular chamber in the structure at the point where the tie member extends through the structure toward the anchor location. The diameter of the annular chamber is larger than the diameter of the tie member so that there is a certain amount of play between the bearing member encircling the tie member and the surface of the annular chamber whereby lateral movement of the tie member can occur. With the tie member anchored in place the space between the outside of the bearing member and the inside surface of the annular chamber can be filled with grout to support the tie member.
