Limiting link type low-frequency shock-isolation energy-dissipating support

Abstract

The invention relates to a limit connecting rod type low frequency vibration isolation energy-consumption support and belongs to the technical field of structural engineering earthquake resistance and vibration reducing. The support comprises a rigid base plate, a disc spring set, a rigid protective cylinder, a horizontal bar, a universal hinge, a tension spring set, a sway rod, a limit spring, a U-shaped bracket and a herringbone damping support. In the condition of normal use, the vibration isolation energy-consumption support disclosed by the invention has higher static stiffness, and is capable of bearing the weight of an upper structure, meanwhile, and the disc spring set generates smaller deformation and transmits load to a lower structure. Under the seismic action, as a connecting rod system composed of the horizontal bar and the sway rod generates negative stiffness under the action of the load, the herringbone damping support has higher static stiffness, the stiffness of the entire system is reduced to be very small by connecting with a negative stiffness mechanism in parallel, the frame structure is enabled to be in low frequency, vibration of the external structure in an earthquake can be effectively controlled, a viscosity damper at the bottom can generate small vibration to dissipate energy of the earthquake, and thus the safety of the whole structure is guaranteed.

Description

technical field [0001] The invention relates to a position-limiting connecting rod type low-frequency shock-isolation energy-consuming support, which belongs to the field of anti-seismic, shock-absorbing and wind-resistant technical fields of building structure engineering. Background technique [0002] Earthquake is an unavoidable natural phenomenon in human society. 90% or more of the casualties and economic losses caused by earthquakes are caused by the collapse of buildings. Therefore, all countries in the world are committed to doing a good job in earthquake resistance and disaster reduction of projects, and are committed to improving the earthquake resistance level of construction projects and improving the earthquake resistance of construction projects. When building buildings in earthquake areas, in order to reduce the potential earthquake threat, it is necessary to carry out seismic design for buildings, among which, adopting seismic isolation design is one of the e...

Problems solved by technology

Most obviously, the use of seismic wall design restricts the ground floor space and consumes manpower

For the arrangement of inter-column supports in industrial plants, the amount of steel used is relatively large, and the arrangement is also relatively complicated. When an earthquake strikes, the vibration control effect is not good, and a good energy consumption effect cannot be achieved.
