Example Embodiment

[0026] Example 1:

[0027] The specific embodiments of the present invention will be described in detail below with reference to the drawings.

[0028] Such as figure 2 Shown here is an embodiment of the self-resetting energy-consuming bridge pier with replaceable transversely configured prestressed tendons of the present invention, which mainly includes prestressed reinforced concrete columns 1, longitudinal prestressed tendons 2, ordinary stirrups 3, rubber layers 4, and reinforced hoop Reinforcement 5, transverse prestressed reinforcement 6, anchorage 7, foundation 8.

[0029] First of all, the precast prestressed reinforced concrete column 1 is equipped with prestressed steel bars and ordinary stirrups 3, and strengthened stirrups 5 are placed where the transverse prestressed tendons 6 pass, and are reserved at the position where the transverse prestressed tendons 6 pass. Tunnel.

[0030] Secondly, for the construction of the foundation 8, the foundation 8 is made of high-streng...

Abstract

The invention discloses a replaceable transversely-arranged prestressing tendon self-resetting energy dissipation bridge pier, and belongs to the field of structural engineering earthquake resistance and reduction. The replaceable transversely-arranged prestressing tendon self-resetting energy dissipation bridge pier comprises a prestressing steel bar concrete column, a longitudinal prestressing tendon, common stirrups, a rubber layer, reinforcing stirrups, transverse prestressing tendons, anchorage devices and a foundation. The transverse prestressing tendons of the bridge pier provide elastic restoring force, meanwhile, the rubber layer dissipates energy of the earthquake under the action of the earthquake, the self-resetting energy dissipation function of the bridge pier under the action of normal loads and the earthquake can be achieved, and finally the energy dissipation and earthquake disaster reduction functions of the whole bridge pier are achieved. The replaceable transversely-arranged prestressing tendon self-resetting energy dissipation bridge pier has the advantages of being capable of conducting self-resetting, being replaceable, reducing the earthquake disaster, dissipating the energy and the like.

Description

technical field [0001] The invention belongs to the field of anti-seismic and shock-absorbing technology of bridge engineering, and relates to a pier with prestressed tendons arranged transversely, and a rubber layer is arranged between the pier and the foundation, so as to realize the self-resetting and energy-dissipating functions of the pier under earthquake action. The invention has low cost, outstanding anti-seismic performance, simple and convenient construction, can effectively prevent falling beams, and has good development prospects. Background technique [0002] In recent years, with the improvement of people's living standards, people's requirements for earthquake resistance and shock absorption have become higher and higher. Especially since the Wenchuan earthquake in 2008, people have paid more and more attention to various disasters caused by earthquakes, not only for buildings but also for The requirements for construction facilities such as bridges are also g...
