Can anyone please advise in quick numbers the load carrying capacity of a bolted connection? There are 2 vertical I columns with a horizontal I beam attached using 6 x M16 bolts at each end...somewhat like a set of goal posts. So the bolts are in single shear. Trying to find out how much weight that could safely hold. I've found that each bolt has a tensile strength somewhere in the order of 8000-9000kg (8.8 grade), so shear would be approx 60% of this? So 4800-5400kg? This can be multiplied by the number of bolts ie 6 in each end...so approx 6 x 5000kg (avg) = 30,000kg.

I know this is very simplistic. Is this in the correct ballpark? Or wildly inaccurate?
