Steel arch concrete simply supported beam

Abstract

The steel arch concrete simply supported beam consists of steel skeleton or steel pipe concrete, high strength steel bar or wire cable, longitudinal steel rib, concrete and hoop rib. The inside steel skeleton or steel pipe concrete has two ends connected to high strength steel bar or wire cable to constitute the key stress part of the steel arch concrete simply supported beam; and the outside of the steel arch concrete simply supported beam has longitudinal steel rib and hoop rib configured and concreted deposited. The steel arch concrete simply supported beam has raised bearing capacity and low cost.

Description

technical field [0001] The invention relates to the field of building structures, in particular to a steel arch concrete simply supported beam that can be directly applied to a transfer floor girder in a high-rise building structure. Background technique [0002] At present, in the structure of high-rise buildings, due to the complex load and stress form of the transfer floor girder, if ordinary reinforced concrete beams are used, a higher reinforcement ratio is generally required, which often leads to difficulties in the arrangement of reinforcement bars, and there may also be over-reinforced beams The hidden danger of brittle failure. [0003] When the above methods cannot meet the bearing capacity or stiffness requirements, steel reinforced concrete beams are often used in engineering to achieve the purpose of increasing bearing capacity and reducing brittle failure. However, steel-reinforced concrete beams use a large amount of steel, and the steel reinforcement near th...

Problems solved by technology

However, steel-reinforced concrete beams use a large amount of steel, and the steel reinforcement near the neutral axis has not yet fully exerted its mechanical properties, resulting in a large waste of materials
