Steel angle steel connection H-section FRP (fiber reinforce plastic) beam-column joint and connection method thereof

Abstract

The invention discloses a steel angle steel connection H-section FRP (fiber reinforce plastic)beam-column joint and a connection method thereof, and belongs to the technical field of civil engineering. The steel angle steel connection H-section FRP beam-column joint comprises an H-shaped FRP column, an H-shaped FRP beam, a pair of flange angle steel, a pair of web angle steel, three sets of high-strength penetration bolts, three sets of high-strength friction bolts, twelve sets of ordinary bolt holes, three sets of oblong bolt holes, and two sets of cushion blocks, the H-shaped FRP beam is composed of an upper wing plate, a web plate, and a lower wing plate, the web plate is located between the upper wing plate and the lower wing plate, each set of the high-strength penetration bolts, thehigh-strength friction bolts, the ordinary bolt holes, and the oblong bolt holes has four members, one set of the cushion blocks has a pair of members, and ductile deformation ability and energy consumption ability are high.

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...
