Abstract

The invention relates to the field of bridge engineering, and specifically discloses a multi-stage energy-consuming horizontal swing pier, including a support and a pier body. The pier body includes a supporting pier and several segmented piers, and the supporting pier and the segmented pier are both hollow structures. , the lowermost segmented pier is fixedly connected with the supporting pier, the upper end of the segmented pier is provided with a circular ladder groove, and the lower end of the segmented pier is provided with a cylindrical stopper, the diameter of the stopper Smaller than the inner diameter of the circular ladder groove, several segmental piers overlap one another, and the uppermost segmental piers can support the bearings. The purpose of the invention is to solve the technical problem that the existing ductility design causes more serious damage to the bridge under the action of strong earthquakes.

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...
