摘要： An economic and efficient method for providing an inner constrained layer damping system to a tubular structure by inserting an inner damping tube that has been substantially slit along its length at several places around its circumference and then wrapped in a viscoelastic tape to cover the slits, or just plain tape to just cover the slits, with a viscoelastic layer thereupon with the tape inserted within and coextensively along the inside of the outer structural beam to be damped, and with the space between the two filled with a replicating material such as epoxy, cement grout, rubber, or other pourable or injectable material, which must have high shear damping properties if the latter tape-just- covering-the-slit option is used, to couple in shear the outer structural beam to the inner slit damping tube and cause shear strains to be transmitted across the viscoelastic boundary between the two tubes.
