Structural reinforcement for long-lasting structures
The additional of metallic products to the Fyfe's structural strengthening solutions enables us to deliver a more robust range of options to the structural strengthening industry.
We have recently launched Duktil FRP Anchor Plates which sit alongside Tyfo Ti NSM Bars that we brought to market in late 2024.
Tyfo Ti NSM Bars
The Tyfo Ti NSM bars are an aerospace grade alloy consisting of Titanium, 6% Aluminum and 4% Vanadium (commonly referred to as Ti-6Al-4V) used to strengthen reinforced concrete structures (e.g. slabs, beams, walls, columns and diaphragms).
These bars provide ductility, are high strength, light-weight tension members that do not corrode and do not fatigue. The Tyfo Ti NSM bars are typically bonded in grooves cut into the concrete cover of an existing structural element using a technique called Near Surface Mounting or NSM strengthening. The bars can be bent at the ends to provide anchorage and are designed to increase the structural performance as required by the engineer of record.
Tyfo Ti NSM bars:
- Provides a ductile strengthening alternative where externally bonded FRP is not suitable
- Improve flexural and shear capacity of existing concrete beam, slab, column and wall elements
- Extend the life of the structure
- Can be bent at the ends to provide anchorage.
Duktil FRP Anchor Plates
Duktil FRP Anchor Plates are hybrid steel/FRP plate systems engineered to provide an alternate load delivery from externally bonded FRP into concrete. The system bonds directly to the LOCTITE Tyfo Composite systems using LOCTITE Tyfo S epoxy. It is then anchored into the concrete substrate using Hilti’s KBTZ2 wedge anchors or KH-EZ-C screw anchors.
The system was developed to improve the overall performance of FRP Systems when used in retrofitting structures. The system provides an increased performance beyond traditional FRP bonding and anchorage provided by conventional FRP anchors.
While strength is its primary objective, it also provides ductility given the deformation and slotting of its metallic components: The plates will deform before the anchor fails ensuring the FRP remains bonded to the concrete and providing for easy visually apparent inspection not possible with standard FRP systems.
The Duktil FRP Anchor Plate system has been extensively tested to ensure its structural performance. To date, it has proven to be the most effective method to anchor externally applied FRP systems to concrete. It has the potential to fully develop up to four layers of the LOCTITE Tyfo SCH 41 System and can accommodate larger strains. Minimum design properties have been evaluated and now form part of ICC-E.S.R. 2103 report.
