Description

technical field

[0001] The invention relates to the technical field of civil engineering, and more specifically relates to a steel angle steel connection H-section FRP beam-column node and a connection method thereof. 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. Great addition to structural materials. Rationally applying FRP to various structures has become an important direction for the development of engineering structure applications.

[0003] Although most of the current FRP research focuses on the repair of existing projects, the seismic reinforcement of structures, and the pavement of bridge decks, etc. However, with the commercialization of pultrusion technology, pultrusion FRP (ie PFRP) components a...
