<p>METHOD AND APPARATUS FOR GUYING A LOAD BEARING MEMBER A system for guying a tower on which a force is exerted in a direction transverse to the elongate dimension thereof includes a plurality of guys interconnected between the tower and respective anchors. The guys are placed under a tension load to oppose the force exerted on the tower. An extensible device, such as a hydraulic piston and cylinder assembly, is serially interconnected with the guys at a location between the tower and the anchor. Before a force is exerted on the tower, the piston and cylinder assemblies are pre-pressurized with hydraulic fluid so as to retract the pistons and thus reduce the effective length of the guys. When the load on the guy bearing the greatest tension load reaches a predetermined value, hydraulic fluid is relieved from its associated piston and cylinder assembly, allowing the assembly to extend and increase the effective length of that guy. As this occurs, the tower will translate in the direction of the load exerted thereon, transferring a portion of the tension load that would otherwise be borne by the guy bearing the greatest load to the remaining guys. The tension load at which the piston and cylinder assembly extends is predetermined so as to prevent the tension load per unit crosssectional area of its associated guy from exceeding the ultimate strength of that guy.</p> |
