Locally-embedded steel pipe concrete column type aseismatic bridge pier

TLDR: In this article, a locally-embedded steel pipe concrete column type aseismatic bridge pier is proposed, which consists of longitudinal ribs, stirrups, steel pipes, common strength concrete, high strength concrete and a bridge pier foundation.

Abstract: The invention provides a locally-embedded steel pipe concrete column type aseismatic bridge pier, and belongs to the technical field of structural design of bridges. The aseismatic bridge pier comprises longitudinal ribs, stirrups, steel pipes, common strength concrete, high strength concrete and a bridge pier foundation. According to the bridge pier, a steel pipe concrete column is locally embedded to the reinforced concrete bridge pier, the advantage of high ductility of the common strength concrete bridge pier and the advantages of high pressure resistance, high shear resisting, high bearing capacity and high ductility of the steel pipe high strength concrete are fully utilized, and therefore, the shear resistance, the pressure resistance, the bearing capacity, the ductility and the energy consumption capacity of the bridge pier can be improved, the bridge pier can be avoided shearing damaging and bending conquassation, and as a result, the aseismatic performance of the reinforced concrete bridge pier can be effectively improved; the steel pipe concrete column is embedded in the local maximum force bearing range of the bridge pier, so that the purpose of the improving the aseismatic performance of the bridge pier is achieved, and the purpose of minimizing the cost of the bridge pier and the construction difficulty can be reached. The bridge pier can be widely applied to the field of bridge construction design.
