AI Technical Summary
Traditional earthquake-resistant facilities are prone to concentrated damage and insufficient energy dissipation. Reinforced concrete structures have poor ductility, are difficult to construct, and are costly. Traditional dampers or energy dissipation devices affect the normal use of the structure. Modern civil engineering and infrastructure require more effective earthquake resistance and vibration reduction solutions.
The assembly friction type holographic energy dissipation and vibration reduction structure with mortise and tenon joints at the ends of the components is adopted. The holographic substructure first dissipates energy, and the friction deformation and bending of the mortise and tenon structure dissipate energy to achieve a strong column and weak beam design. Combined with prefabricated beam and column components and high-strength steel connectors, a nested system of main frame and holographic subframe is formed.
Under multidimensional seismic action, the substructure consumes energy first, reducing damage to the main structure, ensuring the overall stability and safety of the building, reducing construction costs, and improving construction efficiency and maintenance convenience.
