AI Technical Summary
Independent column support systems exhibit significant residual deformation under external loads and strong earthquakes, making structural repair difficult and costly, and hindering rapid post-earthquake recovery.
A self-balancing independent column support system with dampers is adopted. The support platform is formed by high-strength thin-walled steel plates. Combined with the energy dissipation of the dampers, self-resetting and vibration reduction are achieved. Self-balancing is achieved by using prestress and geometric optimization. The dampers are designed to be detachable to extend the structural life.
It improves the ductility and energy dissipation capacity of the support system, reduces the structural weight, reduces carbon emissions, and extends the structural lifespan, making it suitable for multi-hazard protection and rapid deployment of emergency structures.
