Embodiment

[0027] A multi-stage energy-dissipating horizontal swing pier includes a support 1 and a pier body.

[0028] The pier body includes a supporting pier 3 and several segmented pier 2, both of which are hollow structures. Wherein the length of the supporting pier 3 is much longer than that of the segmented pier 2, and the segmented pier 2 consists of four pieces, and the lowermost segmented pier 2 is fixedly connected with the supporting pier 3. The upper end of the segmented bridge pier 2 is provided with a circular ladder groove 4, and the lower end of the segmented bridge pier 2 is integrally formed with a cylindrical stop cylinder 5, the diameter of the limit tube 5 is smaller than the inner diameter of the circular ladder groove 4, and several segmented bridge piers 2 overlap up and down, and the uppermost segmented pier 2 can support the bearing 1. The bottom of the circular ladder groove 4 is provided with a cavity 6, the bottom of the cavity 6 is fixedly provided with an...

Abstract

The invention relates to the field of bridge engineering, and particularly discloses a multi-section type energy dissipation horizontal swing pier which comprises a support and a pier body. The pier body comprises a supporting pier and a plurality of subsection piers, the supporting pier and the subsection piers are hollow structures, and the lowermost subsection pier is fixedly connected with thesupporting pier. A circular ladder groove is formed in the upper end of each subsection pier, a cylindrical limiting cylinder is arranged at the lower end of each subsection pier, the diameter of each limiting cylinder is smaller than the inner diameter of the corresponding circular ladder groove, the subsection piers are overlapped up and down, and the uppermost subsection pier can support the support. The invention aims to solve the technical problem that an existing ductile design causes more serious damage to the bridge under the action of a strong earthquake.

Description

technical field [0001] The invention relates to the field of bridge engineering and specifically discloses a multi-stage energy-consuming horizontal swing pier. Background technique [0002] At present, bridge anti-seismic methods mainly use the selected plastic deformation of the structure to consume seismic energy and prolong the structural period, thereby reducing the seismic response and achieving the effect of earthquake resistance. Now bridge piers are usually designed as ductile components to prevent bridges from collapsing during earthquakes and protect people's lives and properties. However, for medium and low bridge piers, shear failure is prone to occur during earthquake action. In order to avoid shear failure, a large number of stirrups and longitudinal reinforcements need to be configured, which will greatly increase the construction cost. Moreover, the ductile design is to dissipate the seismic energy through the plastic deformation of the plastic hinge, so th...
