Thanks for the reply. Do you know which OSHA document that is? I'm not familiar with that, as OSHA is not widely used in my country (though we adopt the AISC for steel code).
And if we're designing in a high seismic region, is there any effect of high lateral load on the shared bolts? Say where...
Are there any limitations on bolt sharing in a double-sided end plate connection, typically where 2 beams are connected to a column web? I recall that I read somewhere in a code that some structural system forbids the use of shared bolts, although I cannot find the code that states the limitation.
