The invention discloses a self-resetting
pier column
structural system with a built-in energy dissipation
assembly and an implementing method for the self-resetting
pier column
structural system, and belongs to the field of
bridge engineering. The self-resetting
pier column
structural system consists of a pier column, a bridge
abutment, energy dissipation steel bars, non-adhesion prestressed steel bars with an elastic resetting function and an embedded part; in the novel pier column structural
system capable of effectively reducing
residual deformation and ensuring sufficient energy dissipation, a pier is connected with the bridge
abutment through the energy dissipation steel bars and the non-adhesion prestressed steel bars. Compared with the conventional pier column node, the self-resetting pier column structural
system has the advantages that: the non-adhesion prestressed steel bars are positioned in the axle center of the pier column, a self-resetting
restoring force can be generated, and the problem that the conventional pier has large
residual deformation under the action of an earthquake load and cannot serve people any longer can be solved well; the self-resetting pier column structural
system is flexible in design and definite in
structural stress; the pier is ensured to have sufficient strength and rigidity; and the self-resetting pier column structural system can be implemented by a prefabricating or on-site pouring method, is easy and convenient to construct, and is an advanced and practical novel pier column system.
