Steel multi-slit damper with improved seismic and damping performance

Abstract

The invention relates to a steel multi-slit damper with improved anti-seismic and damping performance. When the multi-slit damper is arranged in a structure separated from the top and bottom, the left and right sides face each other, that is, the left and right outer slit dampers and inner slit dampers When the devices are arranged so as to overlap left and right, the inner slit damper is designed so that the yield strength is relatively weak, and the outer slit damper is designed so that the yield strength is relatively stronger than that of the inner slit damper. And, in a state where the upper plate and the lower plate of each slit damper are separated from each other, they are arranged in such a manner that the male and female structures engage with each other up and down. Therefore, even if a strong external force is applied, the damping area of ​​each damper is not broken, and the effect of seismic reinforcement is continuously maintained.

Description

technical field [0001] The invention relates to a steel slit damper, in particular to a steel multi-slit damper capable of effectively absorbing external vibrations affecting buildings and improving the anti-seismic and damping performance. Background technique [0002] Recently, many newly built buildings tend to be high-rise, and considering the effective use of limited land, the phenomenon of high-rise buildings in these buildings is expected to become common in the future. [0003] With the increase in these high-rise buildings, recent earthquakes have occurred frequently in countries neighboring South Korea, which shows that South Korea is not a safe zone for earthquakes. [0004] Therefore, when natural disasters such as earthquakes or typhoons occur, high-rise buildings may suffer greater damage due to vibrations, so there is an urgent need for earthquake resistance, damping, or isolation in buildings as part of these requirements , various shock absorbing devices in...

Problems solved by technology

[0005] However, shock-absorbing devices such as dampers that have been proposed recently have a problem that their structures are too complicated or the shock-absorbing effect is not good.
