A self-resetting energy-dissipating bridge pier with replaceable transversely arranged prestressed tendons

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 technical field of earthquake resistance and damping of bridge engineering, and relates to a bridge pier with transversely configured prestressed tendons, and a rubber layer is arranged between the bridge pier and the foundation, so as to realize the functions of self-reset and energy consumption of the bridge pier under the action of earthquake. The invention has low cost, outstanding seismic performance, simple construction, effective prevention of falling beams, and good development prospects. Background technique [0002] In recent years, with the improvement of people’s living standards, people’s requirements for earthquake resistance and damping have become higher and higher. Especially since the Wenchuan earthquake in 2008, various disasters caused by the earthquake have attracted more and more attention, not only for buildings but also The requirements for bridges and other construction facilities are also getting higher...

Problems solved by technology

However, this method has little effect on large-scale earthquakes. At present, there is no effective anti-seismic and shock-absorbing device to prevent the damage of bridge piers under earthquake action. In short, the earthquake-proof effect of bridge piers is not obvious at present.
