New Hybrid Energy Dissipation Shock Absorbing Support

Abstract

The invention relates to a novel compound energy-dissipation and shock-reduction support. The novel compound energy-dissipation and shake-reduction support comprises a core veneer, an outer sleeve, L-shaped steel plates, rectangular steel plates, viscous-elastic materials and bolt holes. The outer sleeve is sleeved outside the low-yield steel core veneer, the rectangular steel plates are welded on one sides of ends of the outer sleeve. The viscous-elastic materials are filled between the rectangular steel plates and the L-shaped steel plates. The L-shaped steel plates are welded with the core veneer and are connected with the structure through the bolt holes formed in two ends of the core veneer. The support cannot lead to buckling when bearing pressure under the action of earthquake. The low-yield steel core veneer generates repeated tension pressing deformation, meanwhile the viscous-elastic materials generate shear deformation, and the low-yield steel core veneer and the viscous-elastic materials dissipate earthquake energy together. The viscous-elastic materials begin to dissipate energy once relative displacement happens between the outer sleeve and the core veneer. Under the same deformation condition, the viscous-elastic materials and the buckling-restrained support dissipate energy together, and the support has a larger energy-dissipation capacity compared with a traditional buckling-restrained support. A layer number and a size of a viscous-elastic material layer can be flexibly designed according to need.

Description

technical field [0001] The invention relates to a novel hybrid energy-dissipating shock-absorbing support, which belongs to the technical field of anti-seismic and energy-dissipating shock-absorbing engineering structures. Background technique [0002] In the process of resisting earthquakes, traditional structures consume the energy input by earthquake vibrations through the nonlinear deformation and damage of the building structure system. This is an anti-seismic strategy that relies on the structure itself. The anti-seismic effect is not significant enough, and it will cause damage to the structural system, resulting in a large post-earthquake repair cost. With the development of structural shock-absorbing technology, shock-absorbing and isolating devices are being widely used. The principle is to consume or isolate a considerable part of seismic energy through shock-absorbing and isolating devices, thereby reducing structural damage and ensuring structural safety.
