Abstract

The invention discloses a novel circular steel tube bridge pier, comprising a circular steel tube bridge pier body, a transverse partition, a buckling-restrained energy dissipation shell and a baseplate which are sequentially welded and fixed together from top to bottom. The buckling-restrained energy dissipation shell comprises a plurality of high-strength steel curved plates and a plurality of low-yield-point steel curved plates; the high-strength steel curved plates and the low-yield-point steel curved plates are alternatively distributed to define the buckling-restrained energy dissipation shell, and the outer surfaces of the low-yield-point steel curved plates are tangent to the outer surfaces of the high-strength steel curved plates; an inner restraining curved steel plate and an outer restraining curved steel plate are fixedly locked to the inner and outer sides of each low-yield-point steel curved plate; the radii of the inner and outer restraining curved steel plates are identical with those of the low-yield-point steel curved plates. The circular steel tube bridge pier has good earthquake resistant performances, can be detected and repaired rapidly after earthquakes, and can be conveniently popularized and applied in the practical engineering.

Description

technical field

[0001] The invention relates to the energy-dissipating structural form of a steel pier in the field of civil engineering, in particular to a circular steel pipe pier with an anti-buckling energy-dissipating shell at the root, and belongs to the technical field of steel pier in bridge engineering. Background technique

[0002] The previous experience of earthquake damage at home and abroad shows that bridges are vulnerable to earthquakes. The bridge pier is the main load-bearing structure of the bridge structure, and its damage plays a decisive role in the damage or even destruction of the bridge structure as a whole. Serious damage to bridge piers may cause bridge collapse, and it is difficult to repair and use in time after the earthquake, which will bring troubles to rescue and disaster relief after the earthquake, and the resulting losses are often very huge.

[0003] At present, bridge piers at home and abroad generally adopt the form of reinforced concr...
