Description

Reinforced concrete structure, beam, column and building

Technical Field

The utility model belongs to the building field especially relates to a reinforced concrete structure, roof beam, post and building.

Background

A reinforced concrete structure refers to a structure made of concrete reinforced with steel bars. Wherein the steel bars bear tensile forces and the concrete bears compressive forces. The building material has the advantages of firmness, durability, good fireproof performance, steel saving and low cost compared with a steel structure. The two different materials of steel bar and concrete in reinforced concrete structure can work together effectively because of the adhesive force between concrete and steel bar after the concrete is hardened. It is composed of three parts of molecular force (adhesive force), frictional resistance and mechanical bite force. The decisive factor here is the mechanical engagement force, which amounts to more than about half of the total adhesion force. In order to ensure reliable adhesion between the reinforcing steel bars and the concrete and prevent the reinforcing steel bars from being corroded, a concrete protective layer with a certain thickness is required to be arranged around the reinforcing steel bars. If the structure is in an environment with aggressive media, the thickness of the protective layer is increased.

Although the bonding force between the reinforcing steel bars and the concrete ensures the cooperative work between the reinforcing steel bars and the concrete, when an earthquake occurs, the structure needs to have larger deformation and energy consumption capacity, however, the deformation can only occur in a limited range of a crack and a vicinity of the concrete, the reinforcing steel bars and the concrete are completely separated in the limited range, and the stress strain of the reinforcing steel bars is fully exerted. But because of the small number of cracks, the deformation and energy consumption capability are small. Particularly, in the design, the structure needs to be at some parts with large plastic deformation, such as a beam end and a column bottom, a connecting beam in a shear wall structure, a bottom reinforcing area and the like, and if the design is not reasonable, an energy consumption mechanism or an energy consumption system required by the design cannot be formed sufficiently. Although the energy dissipation and shock absorption devices such as the damper can achieve the effects of increasing the structural damping and improving the energy consumption capability of the structure, the damper is high in product cost and large in design difficulty, and is not suitable for most common house buildings.

Therefore, there is a need for an economical and efficient reinforced concrete structure that can resist earthquake.
