I know there have been a few threads on TG20 but I have asked this question to a couple of different sources and to be honest got a couple of different answers and I thought I would try the forum. If you look at the pretty pictures in the book you only have 2 options, either single bay with plan brace every 4 lifts or double bay between braced frames, but what about if you brought the braced frame in and ledger braced two standards in a row wherever you have a single sway brace? If you go with the text I reckon that still complies as all it says is "between braced frames" but my real problem is proving it, especially using Cads which only give you the two options. I have never liked anything other than single bay brace and find it awkward trying to change now.
