Problems solved by technology

[0003] During the use of the bridge, vibration will be generated, and the vibration is very harmful to the bridge, especially the bridge pier. When the bridge pier has an anti-seismic effect, it can greatly improve the service life of the bridge. Nowadays, shock absorbers are generally used for the earthquake resistance of bridge piers. The way to alleviate, and the shock absorber has a service life, and it will be greatly reduced if the installation is not in place, affecting the use

Abstract

The invention discloses a seismic material for an FRP-reinforced RC cylinder. The seismic material comprises the following components: Portland cement, silicon powder, mineral powder, EVA, aluminum sulfate powder, styrene butadiene rubber powder, ceramsite, iron powder, marble powder, hollow glass beads, polypropylene fibers, fly ash, bentonite, polymer fibers, steel-wire-like fibers, dibenzoyl peroxide, polytetrafluoroethylene, silicon dioxide and water. The seismic material disclosed by the invention is simple in structure, good in seismic effect and good in weather resistance.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to an anti-seismic material for FRP reinforced RC cylinders. Background technique [0002] The bridge pier is a sub-structure that supports the bridge span structure and transmits the constant section and vehicle live load to the foundation. [0003] During the use of the bridge, vibration will be generated, and the vibration is very harmful to the bridge, especially the bridge pier. When the bridge pier has an anti-seismic effect, it can greatly improve the service life of the bridge. Nowadays, shock absorbers are generally used for the earthquake resistance of bridge piers. The shock absorber has a service life, and it will be greatly reduced if the installation is not in place, which will affect the use. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide an anti-seismic material for FRP reinforced RC cylinder, which has...
