Abstract
Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steel material damper, and more particularly, to a steel material damper capable of effectively absorbing external vibration affecting a building by improving buffering force.
The damper used in the seismic retrofitting method of steel structure or concrete structure used in domestic and foreign countries includes a steel damper (metal damper) which dissipates energy by using a yielding mechanism of steel, a friction damper which uses a friction mechanism as an energy dissipating device (Friction Damper), and viscous damper (Viscous Damper) which dissipates input energy using viscous material showing speed dependence.
With the start of steel dampers, friction dampers, and viscous dampers, vibration dampers have gained widespread acceptance as a way to improve seismic performance of seismic and structural engineering systems for the past 20 years. This trend is increasing.
Therefore, although many types of dampers are proposed recently, there is a problem that the structure is too complicated or the vibration absorbing effect is not high.
The present invention has been conceived to solve the problems of the prior art described above, and it is an object of the present invention to provide a steel damper capable of effectively absorbing external vibration affecting a building by improving a buffering force by crushing a slit, The purpose is to provide.
According to an aspect of the present invention, there is provided a steel damper comprising: a slit steel pipe having a hollow rectangular tube having an inner hollow, a plurality of slits formed on each surface at regular intervals, ; An inner cylinder surrounding the slit steel pipe and having a through hole at the bottom of each of the slit steel pipes; An outer cylinder surrounding the inner cylinder and having a through hole of the slit steel pipe and a protruding fin penetrating through the through hole of the inner cylinder at an inner lower portion of each surface; A lower cap installed at a lower end of the outer cylinder and having a lower connecting rod at a bottom thereof; And an upper cap installed on an upper end of the slit steel pipe and having an upper connecting rod on an upper surface thereof.
Here, the inner cylinder and the outer cylinder have check holes formed on both sides thereof facing each other in the longitudinal direction, respectively.
In the steel damper of the present invention constructed as described above, when a vibration or an impact is transmitted from the outside, the slit of the slit steel pipe is collapsed by the projecting pin provided on the outer cylinder to relieve the impact, There is an advantage that it can be prevented.
