With the increasing service life and functional changes of existing buildings, the reinforcement demand for large concrete structures (such as bridges, dams, high-rise building transfer floors, and heavy industrial plants) is becoming increasingly urgent.
Unlike new construction projects, large-scale concrete reinforcement faces unique challenges such as secondary stress under “defective work” conditions, collaborative work between new and old interfaces, and redistribution of stress in large sections.
This article systematically analyzes the core technical difficulties in the current field of large-scale concrete reinforcement and proposes corresponding countermeasures.
