摘要： The structural member includes a pressure tube (20) either having a cable (144) tensioned between its ends or being mounted within an outer member (14). The pressure tube is mounted such that it can move axially with respect to the cable (144) or the outer tube (11). When the tube is pressurized, some of the force is absorbed in hoop stress in the tube, and some of the force is directed to the ends of the pressure tube and to the cable or the outer member either through a piston arrangement or otherwise. When compressive loads are placed on the system, it can support force up to the preload without exhibiting Euler buckling. The system is useful for long, thin columns and for long beams where rigidity is important. The pressure tube is not subject to compressive loading because its ends are free to move axially without compressing the tube. The pressure tube may be wrapped in high tensile strength uni-directional fiber material to withstand higher hoop stress.
