How did you determine this distribution? Manual analysis really isn't 
sufficient for this because the system is statically indeterminate. The 
usual practice for bolted connections is to assume the transverse shear 
loading is uniformly applied to the bolts because yielding in the most 
heavily loaded fastener will cause subsequent increasing shears to be 
carried by the other bolts.
