Frame damping device including composite damper and composite damper composed of high damping rubber and corrugated web and structured seismic reinforcing method using same {{Steel Damper and Frame-type Damping Device usig the Damper and Reinforcing Method}

The present invention relates to a frame damping device including a composite damper and a composite damper composed of a high damping rubber and a corrugated web, and a seismic reinforcing method using the same, comprising a composite damper comprising a viscoelastic damper using a high damping rubber and a corrugated web. The present invention relates to a frame damping device including a composite damper and a composite damper composed of a high damping rubber and a corrugated web to dissipate energy due to the characteristics of a viscoelastic damper and a steel hysteresis damper, and a structure seismic reinforcing method using the same.

Vibration Control refers to the control of vibration generated by wind or earthquake in the case of buildings, and the structure in which a special device or mechanism is installed for vibration control is called a vibration suppression structure. The purpose of vibration suppression is to improve the safety and habitability of the structure by dissipating the vibration energy input to the structure due to wind or earthquake.

In the method of vibration suppression, the structure itself is equipped with a function to detect the vibration from the outside and the vibration of the structure according to the active control and the building to reduce the vibration of the structure by applying a control force corresponding to the vibration of the structure inside or outside the structure. There is a manual control to control the dynamic response of the building by installing additional energy dissipation devices to improve the damping performance of the structure.

Passive vibration dampers can be divided into mass tuning type and energy dissipation type. The former is mainly installed on the top of the building, mainly for the purpose of enhancing the wind habitability, the latter is mainly installed on each floor is used to increase the safety of the earthquake and the wind habitability.

The energy dissipation type vibration suppressor can be divided into displacement-dependent and speed-dependent. The displacement-dependent device uses energy dissipation characteristics due to frictional forces between materials or plastic deformation of metal, and speed-dependent type is used when viscous and viscoelastic materials deform. Heat is generated, and the energy dissipated by using the characteristic of dissipating vibration energy is large in proportion to the speed.

Hydraulic damper, which is a kind of speed-dependent vibration damping device, has superior seismic performance compared to the composite damper, and is mainly used in Japan, where heavy and heavy earthquakes occur frequently throughout the country. However, since such a hydraulic damper is expensive, it is an excessively unnecessary method in Korea, where the frequency of earthquakes is low and the strength of the earthquake is not high. On the other hand, the composite damper has a somewhat lower seismic performance than the hydraulic damper, but the construction cost is low, so it is used for reinforcing steel structures.

However, the above-described vibration damping structure using the composite damper is a type of brace shape, which causes spatial obstacles and is not suitable for the variable structure, and has a disadvantage in that replacement after an earthquake is cumbersome. Therefore, it is difficult to apply to the vibration suppression structure of RC structure that requires a variable structure, and it is inefficient to reinstall the vibration suppression device after the earthquake.

As a background technology of the present invention, there is a patent registration 10-1070043 'Pillar-type damper for improving the seismic performance of the building' (Patent Document 1). This patent devises a column-type damper so as not to cause spatial obstacles. In particular, it proposes a column-type damper in which micro and macro fibers are added to cement paste or cement mortar to improve the seismic performance of a building. The pillar-type damper proposed by this patent has superior ability to suppress or delay cracking under design load and additional load, compared to existing cement composites, which has excellent permeability and durability, and improved energy dissipation and damage control. However, when compared with other materials, there were problems such as the ductility of the cement composite and non-environmental waste generated when the damper in the form of a pillar after the earthquake was required to be replaced.
