Reinforced concrete structure, beam, column and building

Abstract

The invention discloses a reinforced concrete structure, a beam, a column and a building, and is characterized in that the surface of rebar at a position where a plastic hinge is to be formed is painted with oil paint or added with a sleeve, such as two ends of the beam and the bottom of the column, so as to form an unbonded section of the rebar and concrete and additional rebar for preventing theconcrete from cracking prematurely. The structure provided by the invention is simple in construction process and low in increment cost; compared with the traditional reinforced concrete structure, the ductility and energy-dissipating capacity of the structure provided by the invention are greatly enhanced while the bearing capacity of the structure is not reduced. In addition, by painting anti-rusting oil paint or adding a plastic sleeve on the outside surface of the unbonded rebar, the effect of preventing the rebar from rusting can be realized. In consideration of the situation that the unbonded section may crack prematurely to affect the normal use, the additional rebar is arranged at the unbonded section.

Description

technical field [0001] The invention belongs to the field of construction, and in particular relates to a reinforced concrete structure, a beam, a column and a building. Background technique [0002] Reinforced concrete structures are structures made of concrete reinforced with steel bars. Among them, the steel bears the tension and the concrete bears the compression. This kind of building material has the advantages of firmness, durability, good fire resistance, saving steel and low cost compared with steel structures. In reinforced concrete structures, two materials with different properties, steel bars and concrete, can work together effectively because of the bonding force between the concrete and the steel bars after the concrete has hardened. It consists of three parts: molecular force (glue force), friction resistance and mechanical bite force. Among them, the decisive role is the mechanical bite force, which accounts for more than half of the total bonding force. ...

Problems solved by technology

[0005] The purpose of the present invention is to provide a reinforced concrete structure, which is used to solve the problem of using dampers and other energy-dissipating and shock-absorbing devices in the prior art, although the effect of increasing structural damping and improving the energy dissipation capacity of the structure is high, but the product cost of the damper is high , The design is difficult, and it is not suitable for the vast majority of ordinary housing construction and other issues
