Ignacio - I really didn't want this thread to be about LBC but I'm not sure about a SR number. We let our sales rep know that we were having a number of issues with LBC and we were assigned a BrIM Support Engineer to contact directly. The negative moment issue occurred about a year or so ago and everything went through him. Long story short, we were given a patch to fix the issue but we were disappointed on how Bentley advertised that A - a patch was even needed and B - it was available to download. The next version release of LBC included the fix but there was a gap between that was worrisome.
Since then, we've been using older versions of Conspan and RC Pier that we trust, supplementing with spreadsheets to keep currenty with AASHTO. My company has been testing out PGSuper recently. I haven't personally tried it yet but it sounds like its been impressive and moving forward it will be our concrete superstructure program (It being a free program doesn't hurt either - thanks WSDOT). But for pier designs, we're still using RC Pier with the workarounds I described. This isn't really that bad, especially when the pier is short and the wind loading is simple (Kz = 1.0). But if there is another program that can do piers, it'd be nice to fully move on.
