Description

LAMPEL TYPE DAMPER USING MULTI-LEVEL SLIP OF FRICTION MATERIAL}

The present invention relates to a pulsation damping damper capable of multi-stage slip using a friction pad. Specifically, a friction member having a different friction force according to the strength of a load is installed in a pulsation beam formed between walls, and slips in multiple stages. The present invention relates to a pulverization damping damper capable of multi-stage slip using a friction pad that is capable of responding to both wind and seismic loads by sequential operation and accumulation of each friction member after generation.

Recently, with the spread of concerns about earthquake damage, seismic design of buildings and bridges has attracted attention. Seismic design is a comprehensive construction method to protect various structures from the impact of earthquake, and if it is classified in detail, it can be divided into seismic design, vibration suppression, and seismic design.

First of all, the seismic design includes a seismic design and a vibration damping design in a broad sense. However, if the meaning is narrowed down, it can be explained only by the design technique that overcomes the earthquake load through the strength of the structure itself. This seismic design increases the strength and toughness of various members constituting the structure, thereby increasing the rigidity of the structure itself, thereby maintaining structural stability and usability of the structure from earthquake loads.

However, in the seismic design, since a member having a large cross section is used to increase the strength and toughness of the member constituting the structure, or a lot of rebar is consumed, the quantity is increased and economic efficiency is lowered. In particular, earthquake-resistant performance is being questioned in overseas cases where earthquake-resistant structures are collapsed by earthquakes.

In comparison with such a seismic design, the damping and seismic design is an advanced technology for reinforcing the economic performance and the seismic performance by the existing seismic design, and its use has recently been increased.

Among these, the vibration suppression design is a structure for dissipating the seismic load applied to the structure. That is, it is a design method to reduce the earthquake load by artificially adjusting the frequency of the structure according to the vibration characteristics of the seismic wave to prevent the resonance of the structure and further canceling the vibration of the structure and the vibration of the seismic wave.

Recently, in order to minimize interference in terms of the construction plan of the damper installation, dampers, that is, a barrier-type damper installed in the barrier beams have been developed. The pulverization damping damper developed during domestic earthquake loads includes steel damper and friction damper.

Conventional pulverized friction dampers have steel beams instead of concrete girder beams, which have pin points at both ends of steel beams connected to shear walls, and distribute friction pads around the pins to dissipate energy during an earthquake.

In general, dampers can be classified according to control loads. Viscoelastic dampers and viscous dampers are used for wind load control, and steel dampers and friction dampers are used for seismic load control. Therefore, in the case of a weak earthquake and vibration caused by wind load, as in Korea, the earthquake and wind vibration control dampers should be installed respectively, which may increase the construction cost due to the increase in the number of dampers. Recently, in order to increase the operating range of the damper and reduce the quantity of water, a combined pressure damper that can simultaneously control the earthquake and the wind load by combining the wind load damper and the earthquake load damper has been developed. Most of the developed damping composite dampers have combined problems of wind dampers and earthquake dampers, and complex mechanisms and cost increases due to heterogeneous dampers.

The present invention is to solve the above problems, mechanically simple, simple operation mechanism is installed in the pulverization damper formed between the wall and the friction of the damping damper having a different friction force according to the strength of the load It provides a damping damping damper with multi-stage slip using a friction pad that allows the members to slip in multiple stages and after the slip occurs, sequential operation and accumulation of each friction member to cope with both wind and earthquake loads.
