This is AVIGNA’s Proprietary System which is used for high strength applications of bridges. An innovative, easy to operate and highly efficient is an engineering marvel to increases strength of the beams and spans of long bridges.

The Carbon Fiber Reinforced Plastic pre-stressing system includes carbon fiber plate, rigid anchorages and adhesive.

The anchorage system includes fixed-end (dead-end) and stressing-end (live-end) anchorages which are fixed (bolted) to the surface of the concrete structure.

The CFRP Plate is held at each anchorage with clamping jaws, tensioned with hydraulic jacks, and then bonded to the concrete surface. This system is effective in carrying portion of the load that exist on the structure during the installation of the CFRP system.

Characteristics of the Pre-stressed carbon fiber plate reinforcement system:

• High strength carbon fiber plate, increase loading carrying capacity significantly.
• Achieve high forces in carbon fiber plates, by pre-stressing.
• Active loading by pre-stressing, no strain lagging.
• Achieve reverse bending moment, offset part of existing loading, increase stiffness, reduce deformation and deflection of members.
• Reduce cracks, close and stop cracking.

Application Range:

• Long span structures on highways, expressways, railways bridges, commercial buildings etc.
• Ideal for structures where portion of the dead load needs be carried by the cfrp strengthened members.

Application Areas:

• Private Buildings.
• Public Buildings.
• Transportation Infrastructures, such bridges, metros and monorails etc.

A proprietary system of Avigna. Avigna is qualified and certified to apply and use this system for critical projects especially around transportation infrastructures.
