Application Of CFRP For Structural Strengthening & Retrofiting

CFRP for building

Slab

1. Slab — Adds collector reinforcement, negative and positive moment flexural capacity

2. Slab opening — Trim reinforcement

Beam

1. Beam — Laminates or fabrics for flexure and/or collector reinforcement, fabrics for shear stirrup reinforcement and potential use of FRP anchors (shown in orange for contrast)

Wall

1. Wall — Stiffening, flexural, shear or tensile reinforcement

2. New wall opening — Trim reinforcement

Column

1. Column wrapping — Full column wrap to achieve required strengthening, possibly with additional near-surface mounted laminates or fabric for flexure; effective solution for under-reinforced column ties

CFRP for bridge

Carbon fiber reinforced steel: It is a structural material for newly built bridges, with high corrosion resistance, which can bring longer service life and higher structural strength, and reduce material costs.

Carbon fiber steel cables: The steel cables used in suspension bridges and cable-stayed bridges have high corrosion resistance, high strength, high rigidity, and significantly reduced weight, which can bring about a longer service life.

Carbon fiber plate: Through the use of carbon fiber laminated boards for structural reinforcement, corresponding to the repair of load, damage, and deterioration caused by increased traffic flow.

Carbon fiber reinforced fabric: Structural reinforcement and seismic resistance are improved through carbon fiber woven fabric and UD, improving load-bearing capacity, and subsequently reducing cracking and tilting.

Carbon fiber cement: The addition of carbon fiber mesh structure to cement enhances and repairs the load-bearing capacity, thereby reducing cracking and improving corrosion resistance.

Carbon fiber grid: improve the durability of cement and asphalt pavement, which can meet the special needs of high-strength pavement, airport Taxiway and thin pavement.
