  • Bidirectional collapse-proof damper with macroscopic NPR structure and bridge structure having same
    Patent number: 11739810
    Abstract: The present invention discloses a bidirectional collapse-proof damper with a macroscopic NPR structure and a bridge structure having the same, comprising a sleeve and a sliding rod; by adding a structure of a reducing part and a limiting body, a sliding gap exists between both ends of the limiting body and both inner ends of the reducing part; the rod body is connected with the inner side wall of the sleeve through an elastic element; the limiting body and the rod body can realize bidirectional slip in the sleeve, which have multi-level seismic performance.
