Abstract

The invention discloses a reaming bonded reinforced casing type FRP structure beam-column node, and belongs to the technical field of civil constructions. The reaming bonded reinforced casing type FRPstructure beam-column node comprises a FRP column, a FRP beam, end plates, side plates, sleeves, high-strength penetration bolts, high-strength friction type bolts, common bolt holes, oblong bolt holes and epoxy resin glue; the one pair of end plates are arranged and respectively connected to the left side and the right side of the FRP column; the four pairs of common bolt holes are formed in theleft side and the right side of the FRP column and the pair of the end plates; the six pairs of high-strength penetration bolts are arranged; the four pairs of the high-strength penetration bolts arerespectively in threaded connection between the four pairs of common bolt holes; the one pair of the side plates are arranged and respectively connected to the front side and the rear side of the FRPcolumn; the two pairs of common bolt holes are formed in the front side and the rear side of the FRP column and the one pair of the side plates; and the other two pairs of the high-strength penetration bolts are connected between the two pairs of common bolt holes. The reaming bonded reinforced casing type beam-column node has strong ductility deformation capacity and good energy dissipation capacity, and can prevent the FRP beam or the FRP column from brittle failure in a node area under the action of a rare occurrence earthquake.

Description

Technical field

[0001] The present invention relates to the technical field of civil engineering and construction, and more specifically, to a beam-column node of an FRP structure with a reaming and glued joint reinforcement. Background technique

[0002] FRP (fiber reinforced composite material) is a new type of high-performance engineering material that has been successfully applied in civil engineering structures in recent years. It has the advantages of light weight, high strength, corrosion resistance, and convenient construction and molding. It has become a traditional concrete, steel, etc. As an important supplement to structural materials, the rational application of FRP to various structures has become an important direction for the application and development of engineering structures.

[0003] Although most of the current FRP research focuses on the repair of existing projects, the seismic reinforcement of structures, the pavement of bridge decks, etc., with the commerci...
