Problems solved by technology

However, this reinforcement method generally uses FRP reinforcement to achieve corrosion resistance, but FRP reinforcement is a brittle material, which will eventually cause brittle failure of the reinforced column, causing a safety hazard
[0006] After the above-mentioned reinforcement structure and reinforcement system are loaded (fatigue load, earthquake, etc.), the residual deformation of the reinforced concrete column is large, which seriously affects the continued use of the building structure or bridge structure

Abstract

The invention discloses a reinforcement structure and a reinforcement method of a reinforced concrete column. A reinforcement slot is vertically added to the reinforced concrete column to be reinforced, and a filling material is applied in the reinforcement slot; firstly, the filling material is used to clean the The reinforcement slots are filled halfway, put memory alloy rods, press the reinforcement slots into the filling material, fill the reinforcement slots with the filler material, compact and smooth, so that the reinforced concrete columns and the memory alloy rods form One-piece, using the method of near-surface reinforcement, which increases the bonding area between the reinforcing bar and the concrete, reduces the possibility of bond peeling damage, improves the bonding performance of the reinforcing bar and concrete, and utilizes the characteristics of the memory alloy rod itself, It can significantly improve the energy dissipation capacity of the reinforced column, reduce the residual deformation of the concrete column after being stressed, improve the damage self-repair ability of the component, achieve the rapid recovery of the structural function after the earthquake, and realize the semi-active control of the reinforced concrete column.

Description

technical field [0001] The invention relates to the fields of building structures and bridge structures, in particular to a reinforced concrete column reinforcement structure and a reinforcement method. Background technique [0002] In reinforced concrete structures, concrete columns, as the main force-bearing members, play an important role in bearing and transmitting loads. They are important components that affect the collapse and damage of building structures, and their safety directly determines the safety performance of the entire concrete structure. First, due to the influence of man-made or natural disasters such as the improvement of the design code level, poor construction quality, long service time, structural overload, fatigue load, and structural performance degradation caused by steel corrosion in the erosive environment, the building structure is under moderate earthquakes. Collapses and damages are very likely to occur in the center of a major earthquake and ...
