AI Technical Summary
Existing building structure reinforcement technologies suffer from problems such as over-reinforcement of local components, insufficient improvement in overall performance, long construction cycles, high maintenance costs, and poor matching between energy-consuming components and original structural nodes.
The structure is reinforced by an externally attached prestressed prefabricated RCS subframe. Through the combination of precast steel beams, precast concrete columns, energy dissipation devices and steel sleeves, the prefabricated construction process is used to achieve the overall coordinated work of the structure, enhance the lateral stiffness and energy dissipation capacity, and achieve the self-resetting of the structure through prestressed tendons.
It improved construction efficiency and reinforcement quality, optimized the stress and deformation patterns of the structure, realized the centralized transfer of damage and controllable energy consumption, ensured the load-bearing capacity and durability of the structure, and reduced the impact of construction on the original structure.
