Beschreibung
Zusammenfassung:The invention discloses a self-limiting reset composite friction pendulum support with a variable friction coefficient. The self-limiting reset composite friction pendulum support comprises a first energy dissipation pendulum seat, a central energy dissipation block, a second energy dissipation pendulum seat, a high-damping rubber-spring ring, a viscous damper and a shape memory alloy spring. The device has four energy dissipation mechanisms, the central energy dissipation sliding block is located between the first energy dissipation swing seat and the second energy dissipation swing seat, and the friction coefficients of friction plates between the central energy dissipation sliding block and the first energy dissipation swing seat and between the central energy dissipation sliding block and the second energy dissipation swing seat are sequentially increased from inside to outside; the friction coefficient of the friction plate between the stainless steel sliding plate and the stainless steel supporting plat
