Yield-Link® Moment Connection (YL)

The (YL) Yield-Link moment connection is Simpson’s legacy design for resilient structural fuses in a steel moment frame. This product configuration is still available and is qualified to be used on OSPHD/HCAI or DSA projects. If your project does not carry these requirements, please consider our new (YLMC) Yield-Link moment connections, now featuring integrated spacers. Please see the YLMC product information page for more information

At Simpson Strong-Tie, we've built a heritage of steel connection innovation. Through our tireless commitment to technological advancement, research and rigorous testing, our engineers have acquired an unparalleled body of expertise, with more patents and code-listed products than anyone else in the business. Our Yield-Link moment connection is precision-made to meet the tough demands and increased loads of structural steel construction. From building owners to engineers, to contractors and fabricators, the Yield-Link's state-of-the-art design saves everyone time and money — while providing a connection that keeps structural steel buildings strong and safe.

Key Features

  • Saves time and costs on fabrication and erection
  • Requires no onsite welding of moment connection, reducing welding inspection costs
  • Replaceable Yield-Links allow for less costly repairs and shorter recovery times
  • Accepted into AISC 358-16 and code listed in ICC-ES ESR-2802
  • Can be integrated into your design software and can be designed without beam bracing
  • Reduces difficult coordination between welders and inspectors
  • No delays for field welding and welding inspection of the moment connection
  • Small restricted zone for easier MEP coordination
  • All shop welds are fillet welds, providing a simple fabrication process
