Reinforced concrete column reinforcing structure and method

Abstract

The invention discloses a reinforced concrete column reinforcing structure and method. A reinforcing groove is vertically formed in a to-be-reinforced reinforced concrete column, and the interior of the reinforcing groove is coated with a filling material; the clean reinforcing groove is half filled with the filling material, then a memory alloy bar is placed into the clean reinforcing groove, andthe reinforcing groove is pressed into the filling material; then the reinforcing groove is filled with a filling material and compacted and leveled, so that the reinforced concrete column and the memory alloy bar form a whole. A near-surface reinforcing method is adopted, so that the bonding area of a reinforcing rib and the concrete is increased, the possibility of bonding stripping damage is reduced, and the bonding performance of the reinforcing rib and the concrete is improved. The characteristics of the memory alloy bar are utilized so that the energy dissipation capability of the reinforcing column can be remarkably improved, the residual deformation generated after stress of the concrete column is reduced, the damage self-repairing capability of a component is improved, rapid recovery of structure functions after earthquakes is achieved, and semi-active control over the reinforced concrete column is achieved.

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 ...

AI Technical Summary

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
