02 Feb 2007Pins in Holes2 Background Properly preloaded bolts have preliminarily been shown to secure their region of the flanges. Requires Friction  ~0.25 at A-B & B-C Preliminary results show A-A could be trouble C-C is TBD Still need to develop a method of securing the inboard legs, which works with less than ideal fit- up (gaps) To this end, we offer Pins in Holes Shear Panels
