About Tyfo®
Since 1988, The Tyfo® Fibrwrap® Systems have been tested and proven for effectiveness and durability. The Tyfo® systems have had proven success on many projects thoughout New Zealand since 1995. Over 500 structural and material tests, both destructive and non‑destructive, have been performed on the Tyfo® Fibrwrap® Systems.
These include full-scale structural testing for a variety of design goals, long-term environmental durability testing, and in-situ testing of actual installations. The result is reliable composite strengthening systems that have demonstrated intended design performances.
The Tyfo® Fibrwrap® System is an ideal method to improve the seismic performance of buildings including URM structures. The high strength to weight ratio of composite materials allow for significant increase in performance, while adding minimal dead weight to the structure. Additional shear capacity, flexural capacity and rotational capacity can be added to columns, beams, slabs and walls. The Tyfo® Fibrwrap® System can also be designed to act as a drag strut or provide member-to-member shear transfer.
How it works
The Tyfo® Fibrwrap® Systems are comprised of specialised carbon, glass or aramid fabrics and resins, which in unique combination, create composites with tested and proven capabilities.
The Tyfo® Fibrwrap® System can be used to improve the load carrying capacity of a building. Additional shear and flexural capacity can be added to beams, columns, slabs and walls. The Tyfo® AFP System can be used to provide UL tested hourly fire ratings when required.
Areas of application
- Bridges
- Buildings
- Waterfront & marine structures
- Pipes
Tyfo® Fibrwrap® anchoring systems
Concrete Solutions® has utilised Tyfo® Anchors on numerous projects from the anchoring of wet-lay Tyfo® fabrics providing additional development length, to the transfer of loads passing through other building elements.
The fibre anchor concept was invented (US Patent #7,574,840 B1) and developed by Fyfe Co. LLC in order to improve the performance of various Tyfo® Fibrwrap® System designs. The low profile, non-corrosive fibre anchor is manufactured using the Tyfo® SCH (primary carbon) and SEH (primary glass) fibres combined with the Tyfo® S epoxy.
Testing has been conducted by The University of Canterbury New Zealand, The University of Texas at Austin, The University of California at San Diego, The US Army Corps of Engineers, The University of Washington, Washington State University, The University of Patras, Ain Sham University in Cairo and The University of Toronto. Research continues at these and other universities in order to improve and refine Tyfo® Fibrwrap® System designs and details.
Uses
- Develop tension forces though obstacles
- Improve structural performance of beam and wall shear designs
- Improve structural performance of beam and slab flexural designs
- Prevent pullout and/or debonding at ultimate loads
Alkali-silica reaction (ASR)
Concrete Solutions® has successfully rehabilitated structures containing ASR such as bridges by applying Tyfo® wet‑lay fabrics for providing confinement and preventing water from entering into the concrete.
Structural concrete repairs have incorporated the use of Tyfo® products due to their unique properties of being light weight, non-corrosive, applied to the structures exterior and are relatively easy to apply. These properties enable an array of rehabilitation applications including; additional reinforcement to badly spalled concrete, alkali silica reaction (ASR) confinement and preventing chemical attack. Rehabilitation is not just limited to concrete structures but has also included steel and timber structures such as bridges and wharf piles.
Tyfo® rehabilitation of existing structures
Concrete Solutions® is a licenced manufacturer of Tyfo® PR prefabricated standard and split jackets.
Jackets can be manufactured to any given size and structural requirements.
Tyfo® PR jackets & underwater applications
- Thoroughly tested at independent laboratories
- Can prevent the onset of corrosion when applied to new structural elements
- Can be installed below the water line
- Excellent long-term material properties in water
- Can be used on circular, square, rectangular, hexagonal, flared and alternative shaped cross sections
- Cost-effective
Tyfo® prefabricated carbon strips
Tyfo® composite strips are high modulus, high tensile strength pultruded composites which are adhered to the substrate with Tyfo® epoxies.
Tyfo® composite strips are installed for post tensioning buildings, parking structures, bridges and other structures constructed of concrete, wood or steel.
All Tyfo® pultruded composite strips are manufactured using Fyfe Co. LLC products.
Tyfo® blast mitigation & fire protection
Tyfo® Fibrwrap® Systems are ideal for blast mitigation applications.
Their large strain capacities provide ductility at an additional thickness of only a few millimetres. Tyfo® Fibrwrap® Systems can be applied to embassies, chemical plants, petroleum plants, control rooms, grain storage/processing facilities, and other structures to mitigate blast. Structural members that can be enhanced include, but are not limited to, walls, columns, beams, slabs, and roof panels.
Fyfe Co. LLC manufactures the only Fibre Reinforced Polymer products available with Fire Protection which include a Class I Flame and Smoke, 2-hour UL Listed assembly, and 4-hour UL listed assembly. These products are exclusive to the Tyfo® product line.
Concrete Solutions® is well-established in the field of repairing and strengthening buildings and infrastructure with three decades of experience.
Concrete Solutions® is a level 2 Fyfe Co. LLC, Tyfo® certified application company. With our many years of experience of installing Tyfo® Fibre Reinforced Polymer (FRP) products, Concrete Solutions® is capable of assisting you with your strengthening requirements.
Our services include, if required, a free, no obligation preliminary design of the Tyfo® Fibrwrap® System by Fyfe Co. LLC through to project management and installation of Tyfo® Fibrwrap®.
