Benefits of technology

The invention provides a strong and lightweight structure for strengthening building column structures that can easily be assembled. The structure is made of glass fiber or carbon fiber plates that can withstand high levels of force and are resistant to corrosion. The plates can be easily changed in size and shape, making it suitable for a variety of building column structures. Overall, this invention solves the problem of providing a durable and flexible strengthening solution for building column structures that can withstand high levels of force without succumbing to corrosion.

Problems solved by technology

In recent years, many countries including Japan, India, Turkey, Iran and so on have often suffering from earthquakes which cause disasters including casualties and destruction of infrastructures such as bridges.
In addition, it has turned out that other countries including Korea are not safe against earthquakes.
However, in such an elastic design method, since a seismic force, which is one of design variables, is set to be too small, response displacement obtained based on this set seismic force may be remarkably underestimated compared to actual displacement and moment produced by a combination of gravity and bearing power may be also underestimated.
In addition, since stiffness of structures is evaluated based on the entire effective sectional stiffness rather than stiffness measured after the structures are cracked, corresponding response displacement is underestimated.
With the above problems in the conventional bridges, it is almost impossible to tear down, redesign and reconstruct the bridges according to a strict earthquake-resistant design standard due to budgetary limitations although the bridges are in danger of collapse in the event of earthquakes.
However, the above-structured earthquake-resistant strengthening equipment 200 of the conventional bridge lower structure provides a vertical binding force due to pre-stress without consideration of a horizontal binding force, particularly not considering earthquake-resistant strengthening of a fragile central area of the periphery of the bridge lower structure at all and has a problem of difficulty in stacking of the concrete strengthening layer 260 and construction due to manufacture of a separate work bench.
In addition, this above-structured earthquake-resistant strengthening equipment also has other problems of low durability due to external environments such as corrosion, and overweight of the entire earthquake-resistant structure.

Abstract

An earthquake-resistant strengthening structure for building column structures, includes: a plurality of strengthening plates which are made of fiber sheet, are coupled by a concavo-convex structure in a vertical direction and are coupled by a sliding coupler in a horizontal direction; and mortar which strengthens a coupling between the strengthening plates and adheres the strengthening plates to an earthquake-resistant object. The earthquake-resistant strengthening structure is light, can be easily coupled or assembled, and provides a large binding force and tensile force by structural engagement between pieces of the strengthening plates and fusion of bonding materials. In addition, since the strengthening plates are made of glass fiber or carbon fiber, it is possible to provide an optimal earthquake-resistant strengthening structure having high durability, flexibility and strength with no corrosion.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to an earthquake-resistant structure for strengthening building structures, and more particularly, to an optimal earthquake-resistant structure for strengthening building column structures, which is capable of providing high durability, flexibility and strength and no corrosion.[0003]2. Description of the Related Art[0004]In recent years, many countries including Japan, India, Turkey, Iran and so on have often suffering from earthquakes which cause disasters including casualties and destruction of infrastructures such as bridges. In addition, it has turned out that other countries including Korea are not safe against earthquakes. Therefore, there is a current keen need of a seismic design for structures such as bridges according to strict design standards.[0005]Conventional bridges have been designed according to an elastic design method based mainly on allowable stress, without a separate ...
