Anchorage System for Prestressing Non-metallic Tendons

Invention Summary:

The anchorage system has been the biggest challenge for each structural system that involves the use of fiber-reinforced polymer (FRP) tendons. There are many successful designs and systems that been proposed by other teams to anchor and tension these tendons. However, current alternatives are either expensive or hard to fabricate.

Researchers at Rutgers University have developed a novel anchorage system that bonds non-metallic tendons to the sleeve system and secures the force of the tensioned non-metallic tendons using a slotted plate system. The purpose of the technology is to provide an economical anchoring system compared to the few available in the market while also achieving the same results.

Market Applications:

  • Precast prestressed elements using high strength non-corrosive non-metallic tendons
  • Repair and strengthening of deteriorating infrastructure


  • Low cost compared to systems available in the market
  • Simple to use
  • Can be applied in the field; existing alternatives require tendons to be precisely measured and manufactured, or for the concrete to be cast around the tendon in the factory.
