1 HAS-V, HAS-E, and HAS-B threaded rods are considered ductile steel elements( including HDG rods). 2 3 / 8-inch dia. threaded rods are not included in the ASTM F1554 standard. Hilti 3 / 8-inch dia. HAS-V, HAS-E, and HAS-B( incl. HDG) threaded rods meet the chemical composition and mechanical property requirements of ASTM F1554.
5 HAS-R( CW1 and CW2; 3-8-in to 1-in) threaded rods are considered brittle steel elements. 4 Tensile = ϕA se, N f uta as noted in ACI 318-19 17.6.1.2. 5 Shear = ϕ 0.60 A se, V f uta as noted in ACI 318-19 17.7.1.2b. 6 Seismic Shear = α V, seis ϕV sa: Reduction for seismic shear only. See ACI 318 for additional information on seismic applications.
