Description
[0001] The present invention relates to an apparatus for reinforcing an earthquake-proofing structure and an earthquake-proofing method using the same, and more particularly, to a panel zone in which a column and a beam are joined to each other, The present invention relates to an apparatus for reinforcing a panel zone and an earthquake-proofing method using the same, and more particularly to an earthquake-proofing apparatus using the same.
Generally, when designing buildings such as houses, buildings, buildings, apartments, etc., seismic design (earthquake-resistant design) for safely protecting structures from earthquakes will be done together.
However, in Korea, the requirement for earthquake-resistant design for buildings was imposed in 1988. Most of the building structures built before the earthquake were not designed for earthquake-resistant design. Even after the earthquake- It is expected that the collapse of the building structure will lead to massive casualties and damage to property.
Various seismic retrofitting methods are applied to minimize human damage and material damage from earthquakes. As a typical vibration damping method, there is a method of installing a vibration damping device. As a vibration damping device, a braced damper is installed diagonally to dissipate energy by the firing hysteresis behavior when a cyclic load is applied. However, in the conventional method of installing the vibration damper, it is necessary to construct a structural member having a large rigidity such as a column or a beam for supporting a brace type damper. Therefore, it is difficult to install, It has the disadvantage of covering the view.
To improve the disadvantages of the brace type damper, an anti-seismic reinforcement method as shown in Fig. 1 has been proposed. As shown in the figure, a rectangular frame hinged to be rotatable at an edge is fixed to the opening of the building, and a damper is installed to absorb the vibration energy at the inner edge of the rectangular frame and to perform the plastic behavior. This method is advantageous in that modularization is possible, and there is a sufficient space for installing a window by minimizing disturbance of view of residents. However, since the frame and the damper support all the loads, the load distribution efficiency against the seismic force is inferior. Further, in order to effectively reinforce the member, a member having a large cross sectional performance is required, and the corner damper still obscures the view.
SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems of the related art. The purpose is as follows.
First, it is an object of the present invention to improve the seismic performance by increasing the resistance to the lateral force by providing the reinforcing member in the oblique direction or 'X' shape in the panel zone (joining portion of the column and the girder).
Further, the vertical frame further includes a reinforcing member, thereby further improving stability.
Secondly, the structure and the vertical and horizontal frames are coupled to each other by a coupling member having an elastic force, thereby further improving seismic performance.
Especially, since the anti-vibration member having elasticity of various structures is integrally fastened to the bolt part, the structure and the vertical and horizontal frames are combined with each other, thereby enhancing the integrity as well as the resistance against the external impact.
According to an aspect of the present invention, there is provided an anti-seismic steel structure for a structure comprising two pillars, a slab and a girder, comprising: a vertical frame coupled to an inner surface of the column, the member comprising a web connecting both flanges and both flanges; And a horizontal frame coupled to an inner surface of the slab and the girder. A reinforcing member provided between the both flanges and having an oblique or 'X' shape at a vertical frame and a horizontal frame end edge of the frame assembly; And a fastening member for fastening the frame assembly to the structure by a member fixed at predetermined intervals of the structure, wherein the fastening member is a plate-like dustproof structure interposed between the frame assembly and the structure, And a bolt portion having one end fixed to the outer flange of the frame assembly and the other end inserted and fixed in the structure while passing through the anti-vibration member.
According to another aspect of the present invention, there is provided a seismic retrofitting method using a seismic strengthening apparatus using a panel zone reinforcement and an elastic force, comprising: a first step of joining a reinforcement member to a frame assembly; And a second step of securing the frame assembly coupled with the reinforcing member to the inner surface of the structure while fixing the frame assembly with the securing member.
According to the present invention, the following effects are expected.
First, the reinforcing members bracing in a slanting line or 'X' shape are joined to the panel zone corresponding to the connection between the column and the girder, thereby increasing the resistance to the lateral force, thereby improving the seismic performance.
Herein, the vertical frame coupled to the inner surface of the column is further combined with another reinforcing member, thereby further improving seismic performance.
Second, since the structure and the frame are fixed by the fastening member with the anti-vibration member having the elastic force interposed therebetween, the resistance against the external impact is improved and the seismic performance is further improved.
Particularly, since the anti-vibration member is composed of a vibration spring, a spring, and a plate spring together with various elastic members, the anti-vibration member can be suitably applied to various structures and improve structural stability.
