Abstract

The invention relates to a novel reinforced-concrete combined pier column. The combined pier column comprises a fibre-reinforced composite material pipe, wherein a plurality of common reinforcing steel bars and a plurality of fibre bars are arranged in the fibre-reinforced composite material pipe in a distributing way along the length direction of the fibre-reinforced composite material pipe, these common reinforcing steel bars and these fibre bars are all coiled at the middle part in the fibre-reinforced composite material pipe by a plurality of hooping bars, and concrete is poured in the fibre-reinforced composite material pipe. The invention also relates to a corresponding construction method of the novel reinforced-concrete combined pier column. According to the novel reinforced-concrete combined pier column and the construction method of the novel reinforced-concrete combined pier column, the bearing capacity of a pier column structure can be enhanced; moreover, the shock resisting performance of a pier column and the recoverable performance after shock can be effectively enhanced; furthermore, the self weight of the structure is decreased; and the novel reinforced-concrete combined pier column has the characteristic of corrosion resistance under severe environments, such as ocean, humidity, saline-alkali soil and the like.

Description

technical field [0001] The invention relates to a novel reinforced concrete composite pier column and a construction method thereof, belonging to the technical field of structural engineering. Background technique [0002] Bridge piers are the main components of the bridge structure system to resist the lateral force of the earthquake. The direct damage to the bridge piers and the secondary earthquake damage to the superstructure extended therefrom are the main causes of bridge damage in earthquakes. In an earthquake, not only the severely damaged pier needs to be rebuilt, but also the slightly damaged pier with severe residual deformation needs to be rebuilt because the superstructure is difficult to return to its original position. Therefore, the pier structure not only requires high strength and high ductility, but also requires the residual deformation of the pier to be controlled within an appropriate range after the earthquake, so as to facilitate its usability and rep...
