Description

A vibration suppression device and a vibration suppression system including the same {VIBRATION CONTROL APPARATUS AND VIBRATION CONTROL SYSTEM HAVING THE SAME}

The present invention relates to a vibration suppression device and a vibration suppression system including the same.

Recently, earthquakes have occurred frequently in various parts of the world including Japan, which is a neighboring country, and the magnitude and damage of earthquakes are also increasing significantly.

Reports of damage cases caused by earthquakes in various parts of the world show that there is a large difference in the magnitude of human and property damage depending on social preparation for earthquakes and the degree of application of seismic design technology.

Until recently, Korea has been thought of as an earthquake-free area where earthquakes do not occur, but as research and data on earthquake history are accumulated, it is recognized that earthquakes of a certain magnitude or larger can occur in Korea, which can damage people and property. Was done.

In Korea, the number of earthquakes has been steadily increasing so far, and since 2000, it has reached an average of about 50 per year.

In 2013, the number of earthquakes recorded 93 times, and in 2014, an earthquake of magnitude 5.1 occurred off the coast of Taean, Chungcheongnam-do.

In addition, on September 12, 2016, a 5.8 earthquake occurred at a point 8km southwest of Gyeongju, Gyeongsangbuk-do, and this is the largest earthquake ever occurred on the Korean Peninsula after the earthquake observation began in 1978.

According to a report by the Meteorological Administration on October 11, 2016, a total of more than 470 aftershocks, including a 4.5-scale earthquake, continued to occur due to the Gyeongju earthquake, which is similar to the number of earthquakes that occurred from 2007 to 2015.

Even if earthquakes are of the same scale, the degree of damage varies greatly depending on the location of the epicenter, the characteristics of the ground, the surrounding environment and the characteristics of the structure, so it is essential to prepare sufficient preparations for earthquakes and the application of seismic design.

On the other hand, Republic of Korea Patent Registration No. 10-1319698 relates to a cantilever-moving steel damper, which uses the plastic deformation characteristics of the steel, but allows the steel damper to act as a cantilever to dissipate energy, and for the cantilever behavior of the steel damper It is described that one end is fixed with a hinge and the other end with a bolt.
