ABSTRACT:
A laminated hollow rubber damper with increased buckling strength and lengthened period of vibration. The buckling strength of a hollow laminated rubber damper is increased by making at least the inside or the outside wall of the damper of non-uniform section, such as obtained with an arcuately concave wall. By taking advantage of the improved buckling strength of hollow laminated rubber dampers, both the deformability in a horizontal direction and the period of the damper are increased. The hollow laminated rubber damper may be used as a spring element in an active or passive type vibration control device, or as a supporting device suitable for the protection of structures having long natural periods, such as multi-storied buildings.
