For general work in Canada.
It seems like contractors or certain clients like certain types and grades of bolts that are sometimes different that typical specified.
Currently our client wants to use a Class 8.8 Steel Hex Bolt that meats SAE J1199. The project itself is a platform that would be designed using S16-19 - Design of Steel Structures. Within S16-19, connection design solely seems to incorporate A325, A325M, F1852, A490, A490M, F2280, A307. I do think its funny that a Canadian code (metric) uses mostly ASTM or imperial standards other than the metric equivalents of A325M and A490M, mostly since we are so closely ties to the US.
My overall question is when can we differ from what the code allows, and would the same formulas apply to different grades of steel not shown within the standard. Ductility, bearing, tensile, etc would be slightly different for each type of fastener. Engineering judgment is an obvious answer, but is there any sort of document that speaks to this a little bit. I see it happening more often now with issues with supply.
