Description

SFF damper {STABLE FRICTION DAMPER FOR LINTEL BEAM}
The present invention relates to a SF damper, specifically, by installing a separate damping damper on the pulverizing beam to absorb seismic energy, to ensure structural stability from the vibration and shock applied during the earthquake, as well as to reduce the reinforcement The present invention relates to a SF damper that can reduce cost.
Recently, with the spread of concerns about earthquake damage, seismic design of building structures such as buildings and bridges has attracted attention. Earthquake-resistant design is a comprehensive construction method to protect various buildings from the impact of earthquake, and if it is classified in detail, it can be divided into seismic design, seismic isolation, and vibration suppression design.
First of all, the seismic design includes a seismic design and a 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 impact of the earthquake through the strength of the building itself. This seismic design increases the strength and toughness of the various members constituting the building to increase the robustness of the building itself, thereby maintaining structural stability from earthquakes.
In addition, the seismic isolation design is a technique to block or reduce the impact of the earthquake from the ground to the building, also known as earthquake avoidance or seismic isolation structure. Normally, the building is inevitably built on the ground, so it is not possible to completely block the earthquake propagating through the ground, but using the above-described seismic design can significantly mitigate the impact of the earthquake. However, the seismic isolation design is effective for a very strong earthquake and is very expensive.
On the other hand, the vibration suppression design is designed to dissipate the impact of the earthquake on the building, and artificially adjusts the frequency of the building according to the vibration characteristics of the building to prevent resonance of the building, and further cancels the vibration of the building and the vibration of the earthquake wave. It is design method to reduce earthquake shock.
As a vibration damping method for applying the above-described vibration damping design to steel structures or concrete structures, there is a method using a hydraulic damper or a steel damper.
The damping structure using the hydraulic damper is a technology mainly used in Japan, where heavy and strong earthquakes occur frequently throughout the country. The design is excellent so that the external environment is not rough, and the seismic reinforcing performance is excellent. However, the construction cost is high, and considering the frequency or magnitude of domestic earthquakes, the construction method is excessively reinforced.
In addition, the seismic reinforcement method using the steel damper is a technology that has been developed in recent years at home and abroad, compared to the seismic reinforcement method using a hydraulic damper, the construction cost is cheap, and is mainly used for reinforcing steel structures.
By the way, the vibration damping structure using the above-mentioned steel damper is a type of a BRACE shape, the spatial obstacles are generated, it is not suitable for the variable structure, and most have a side that is cumbersome to replace after the earthquake. Therefore, it is difficult to apply the damping structure of RC structure that requires a variable structure, and it is inefficient to reinstall the damping device after the earthquake.
Therefore, there is an urgent need for a new damping damper that can achieve the optimum seismic control effect at a reasonable cost by solving the problems of the damping structure using the hydraulic damper and the damping structure using the steel damper.
The present invention is to solve the above-mentioned problems by installing a separate damping damper on the pulverizing beam to absorb the seismic energy, to ensure structural stability from the vibration and shock applied during the earthquake, as well as to reduce the reinforcement The purpose is to provide a SF damper that can reduce the cost.
The SF damper according to the present invention for achieving the above object includes an SF damper body, which is an I-shaped steel or an H-shaped steel, and a friction material joint installed on a web of the SF damper body. In addition, the friction material joining portion, the mounting groove is formed on at least one side of at least one end portion of the SF damper main body respectively installed on both side plates of the web (web) or flange (flange) plate and the mounting groove is inserted into the web And a friction pad in contact with the fixing plate and a fixing bolt and a nut coupled through the plate plate and the web or the flange.
