Background: ASD 1989 on SC Connections with Fillers • ASD 1989 Section J3.8 on Slip Critical Connections � R n = F v A b N s � F v is from RCSC Specification for oversized: 29 ksi for A490 Class B surface • ASD 1989 Section J6 on Fillers � Exception on developing fillers for slip critical connections, but fills are developed for bearing connections MUST-SIM University of Illinois at Urbana-Champaign December 5, 2007
Background: AISC 2005 on SC Connections with Fillers • AISC 2005 Section J3.8 on Slip Critical Connections � R n = µD uh scT bN s � Connections with standard holes or slots transverse to the direction of the load shall be designed for slip as a serviceability limit state, Ω = 1.50 � Connections with oversized holes or slots parallel to the direction of the load shall be designed to prevent slip at the required strength level, Ω = 1.76 • AISC 2005 Section J5 on Fillers � For fillers with t ≥ ¼” or greater, one of the following shall apply: 1. For fillers with t ≤ ¾”, R n for bolt shear should be reduced by [1-0.4(t-0.25)]. 2. Connection shall be extended and the filler developed 3. Joint shall be extended to equivalent of #2 4. Joint shall be designed to prevent slip at required strength MUST-SIM University of Illinois at Urbana-Champaign December 5, 2007
