A DAMPED ELEMENT

摘要

An element (3) such as cylindrical or non-cylindrical tubular element, a column, or a beam, comprises a layer of plastically deformable energy absorbing material such as lead (2) over at least part of an external and/or internal surface of the element. The layer is bonded to or integral with the surface(s) of the element (3), and is effective to reduce or damp motion or vibration induced in the element.
