Concrete composite column

Abstract

The invention belongs to the technical field of buildings, and specifically relates to a concrete composite column. The concrete composite column provided by the invention comprises a body and a firstreinforcing structural unit, wherein the first reinforcing structural unit is arranged at the outer side of the body; the body is of a hollow structure, and is internally cast with a building material; the body is made of a high-density polyethylene material component; and the first reinforcing structural unit is a fiber reinforced composite material component. Compared with the prior art, the concrete composite column is further improved in bearing force under co-action of the first reinforcing structural unit and the high-density polyethylene material body, is good in vibration resistance and ductility, is smaller in section dimension, is improved in bending resistance of the section, is good in corrosion resistance, and is especially suitable for building, bridge and special structuresunder bad environments such as an ocean environment, a moist environment and saline-alkali soil.

Description

technical field [0001] The invention belongs to the technical field of buildings, and in particular relates to a concrete composite column. Background technique [0002] Earthquakes cause damage or collapse of buildings, which can seriously injure human safety and cause huge property losses. my country is a country with high incidence of earthquakes. How to minimize casualties and property losses caused by earthquakes and improve the ability of civil engineering structures to resist earthquake disasters is a research topic for those skilled in the art. [0003] Fiber-reinforced composites (FRP) have been widely used in concrete structure reinforcement and new construction in recent years due to their small size, light weight, high strength, good corrosion resistance, strong fatigue resistance, and convenient construction. It is hoped that the strength and ductility of the concrete structure can be improved by wrapping FRP strips on the surface of the building, thereby impro...

AI Technical Summary

Problems solved by technology

However, although the concrete structure wrapped by FRP strips has a strengthened stress-strain relationship, its failure mode is brittle and its residual bearing capacity is low, which is still not up to the "multi-level fortification" and performance-based design standards of the current seismic codes in my country. , Insufficient strength and ductility, poor seismic performance of buildings, and not suitable for harsh environments such as ocean, wet and saline-alkali land
