CONCRETE COLUMN OF SEISMIC RETROFIT USING GRID REINFORCEMENT WITH DIRECTIONALITY AND CEMENT MORTAR, AND SEISMIC RETROFIT METHOD FOR THE SAME

摘要

The first grid reinforcement that adds lateral restraint force to the reinforced concrete column, the second grid reinforcement that resists the tensile axial force to reinforce the bending moment, and the third and fourth grid reinforcement that reinforces the shear force are all combined. By placing , it is possible to add a lateral restraining force to the strip reinforcement of the reinforced concrete column, reinforce the bending moment, and simultaneously reinforce the shear force. Also, when fixing the grid reinforcement, an organic adhesive, cured resin, is used. It can be installed on a wet column or in winter without not doing it, and by applying a non-combustible grid reinforcement material, it has superior fire resistance performance compared to the conventional FRP reinforcement coating method, and also has a plastering effect by adding color to the cement mortar. , a reinforcing concrete column using a grid reinforcement having a directionality and a cement mortar, and a method of reinforcing the same.
