This continues to blow me away. Would *anyone* on this list look at that detail and say "Sure, I'd be glad to walk under 10 or 100 tons of concrete hanging from a bunch of epoxy-grouted dowels in tension"????? Not me!
This appears to be even more obviously inadequate than the final hanger detail at the Kansas City Hyatt walkways.
And I don't think this is just good hindsight; I think both of these examples are SO obvious that anyone with more than ten minutes of engineering experience would realize that they're completely inadequate.
