Damped split beam structural member with segmented beam parts

摘要

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.

1. 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.
