TLDR
In this paper, the authors proposed an anti-seismic bridge pier with a locally buried concrete-filled steel tubular column, which belongs to the technical field of bridge structure design.Abstract:
The utility model provides an anti-seismic bridge pier provided with a locally buried concrete-filled steel tubular column, and belongs to the technical field of bridge structure design The anti-seismic bridge pier comprises longitudinal bars, stirrups, normal-strength concrete, high-strength concrete and a bridge pier foundation The concrete-filled steel tubular column is locally buried in a reinforced concrete bridge pier, and the advantage of good ductility of a normal-strength concrete bridge pier and the advantages of high pressure-resistant and shear-resistant bearing capacity and good ductility of a high-strength concrete-filled steel tube are fully utilized, so that the shear-resistant and pressure-resistant bearing capacity, ductility and energy-dissipating capacity of the pier are improved, shear failure and bending collapse of the pier are avoided, and the anti-seismic performance of the pier is effectively improved The concrete-filled steel tubular column is buried in only a local range, with maximum stress, of the pier, so that the purposes of improving the anti-seismic performance of the pier and reducing the construction cost and construction difficulty of the pier as much as possible are achieved The anti-seismic bridge pier can be widely used in the field of bridge project designread more
