Problems solved by technology

The interior of traditional FRP concrete columns is plain concrete or reinforced concrete. Studies have found that under strong earthquakes for these two types of CFST columns, the FRP outer tube will buckle after the built-in concrete is damaged.

Abstract

The invention relates to the technical field of building structural members, and particularly relates to an FRP steel concrete column and steel beam combined joint and a mounting method. The FRP steel concrete column and steel beam combined joint comprises an FRP double-I-shaped steel concrete column, a beam column connecting piece and an H-shaped steel beam, wherein the FRP double-I-shaped steel concrete column comprises an upper FRP double-I-shaped steel concrete column and a lower FRP double-I-shaped steel concrete column which are connected through a connecting cylinder. The FRP steel concrete column and steel beam combined joint is good in corrosion resistance and is assembled through bolt connection after being transported to the site, and the structural integrity and the bearing capacity of the column are improved.

Description

technical field [0001] The invention relates to the technical field of building structural components, in particular to a combined node of an FRP steel concrete column and a steel beam and an installation method. Background technique [0002] With the development of social economy, the construction industry is developing in the direction of optimizing the industrial structure, promoting prefabricated buildings, green buildings, etc., and its transformation has become an inevitable trend of social and economic development. [0003] Although traditional reinforced concrete buildings have strong compressive capacity, they have insufficient bending capacity. The steel tube concrete structure can effectively utilize the respective advantages of steel and concrete, and at the same time overcome the shortcoming that the steel tube structure is prone to local buckling. However, for coastal areas, the steel pipe concrete structure is prone to corrosion problems, which will reduce th...
