| Zusammenfassung: | The multistage anti-seismic pier elastic hinge comprises a lower spherical crown lining support (4), the upper surface of the lower spherical crown lining support (4) is a downwards-concave cambered surface, an upper spherical crown lining plate (3) matched with the downwards-concave cambered surface is arranged on the upper surface of the lower spherical crown lining support (4), and the lower surface of the upper spherical crown lining plate (3) is in a protruding arc shape. The middle part of the convex arc is matched with the concave arc surface on the surface of the lower spherical crown support (4); steel limiting connecting blocks (6) are annularly and vertically arranged at the edge positions between the upper spherical crown lining plate (3) and the lower spherical crown lining support (4) respectively, and a vertical steel spring (5) is arranged between the steel limiting connecting blocks (6) arranged on the two sides of the upper spherical crown lining plate (3) and the lower spherical crown linin |
