The program is great! It would nice to have any 5,6 or 7 bay beam design! I mean to say more then 3 post, as for a long basement layout.
Yes. I've run up against the bay limit too many times.
A newer version of StruCalc may expand upon the 3 bay limit in the future although it is currently not under development.
StruCalc is working on an online version of the program that will have 3+ span analysis available. It won't be developed for the desktop application though. I can't give a delivery time at this point on the online version but stay tuned for updates.
