Problems solved by technology

[0007] Therefore, if prefabricated concrete composite columns can be used to replace some partially filled steel-concrete composite columns, it will be able to greatly solve the existing problems of complex joint connection structure, splicing and formwork construction of partially filled steel-concrete composite columns
[0008] However, traditional prefabricated components are heavy, difficult to splice on site, and have high requirements for on-site construction personnel and construction conditions, and formwork is still required in the joint area of ​​prefabricated components, and the construction process has not been effectively simplified. There are congenital problems such as bond slip and water leakage in the connection, and the use and mechanical performance of the structure cannot be effectively guaranteed

Abstract

The invention discloses partially prefabricated section steel-concrete combined column based on side plate and application of the partially prefabricated section steel-concrete combined column, and belongs to the technical field of buildings. The combined column is good in stress performance, stable in component connection, few and simple in construction process and high in construction efficiency; when the height of the combined column is 3000 mm and the section size is 350 mm*350 mm, the section size of I-shaped steel is 350 mm* 350mm* 6mm; when the thickness of an upper flange and a lower flange is 6 mm, the axial compression ultimate bearing capacity can reach 5733.2 kN, the ultimate flexural bearing capacity can reach 272.5 kN.m, and the ductility coefficient can reach 4.02.

Description

technical field [0001] The invention relates to a partially prefabricated steel-concrete composite column based on a side plate and an application thereof, belonging to the technical field of construction. Background technique [0002] There are many types of composite structures. In a broad sense, a composite structure refers to a structure in which two or more different materials form a structure or component and work together (Composite Structure). Among them, steel-concrete composite structure is the fifth largest type of structure developed after wood structure, masonry structure, reinforced concrete structure and steel structure. [0003] Partially filled steel-concrete composite column is a kind of steel-concrete composite structure, which refers to a steel-concrete composite column composed of I-shaped steel or H-shaped steel and concrete filled in the flanges on both sides, which can give full play to the strength of steel and concrete. The material performance is ...
