Lapped joints would give you more structural integrity above bolts alone, I'd have thought.
My decks going to be a lot smaller than yours (1m deep, 5m wide). I'm going to cheat and have composite joists laying directly on concrete blocks that I have spare. Saves having to do anything too engineeringy.
