Abstract
A structural member includes a split beam within a box structure. The split beam may be a segmented beam that includes multiple segments for each of its parts. Movement of the split beam parts within the box structure, as the structural member flexes, dissipates energy and adds to the damping of the structural member.
Claims20
A structural member comprising:
- an external box structure;
- and
- a split beam within the box structure including longitudinally-split beam parts;
- wherein a beam part is split in a direction substantially perpendicular to the longitudinal split between the beam parts, thereby forming segments;
- and
- wherein the segments of the beam part are separated from one another by gaps, allowing parts of the split beam to shift position relative to each other as the structural member flexes.
3 more elements
A method of dissipating energy in a structural member, the method comprising:
- providing a structural member that includes an external box structure and a split beam within the box structure, wherein the split beam includes a pair of longitudinally-split beam parts, wherein a beam part is split in a direction substantially perpendicular to the longitudinal split between the beam parts, thereby forming segments, and wherein the segments of the beam part are separated from one another by gaps, allowing parts of the split beam to shift position relative to each other as the structural member flexes;
- and
- dissipating energy by relative motion of the beam parts of the beam as the structural member is flexed.
