DRAFT Bill of Materials.xlsx

This is a Draft Bill of Materials document that specifies the components and materials required for two structural connection assemblies being manufactured for the National Institute of Standards and Technology (NIST) National Full-Scale Research Laboratory (NFRL): a Threaded Rod Connection and a Bar Coupler Connection. Both assemblies are designed for precast concrete moment frame testing.

The Threaded Rod Connection assembly includes ASTM A36 steel plates, DYWIDAG threadbar couplers and threaded rods (ASTM A722, Fu = 150 ksi) supplied by DYWIDAG Systems International USA, Inc., corrugated ducts, steel tubes, neoprene bearing pads, and torsion rods with associated hardware. The Bar Coupler Connection assembly specifies No. 10 A706 Grade 80 reinforcement bars with upset ends supplied by Headed Reinforcement Corp., including link bars, continuity bars, debonding sleeves, and shims to accommodate up to one-inch gaps, along with shared components such as armoring angles, steel tubes, bearing pads, and torsion rods. Key materials conform to industry standards including ASTM A36 for structural steel, ASTM A722 for threadbar, and A706 Grade 80 for reinforcing bars. The document indicates that NIST will purchase and install certain components such as load cell washers and spherical washers during assembly. Some components are designated for delivery to NIST, while quantities and specifications are provided for all materials needed to fabricate both connection types for structural testing purposes.
