Hi All,
I'm designing a typical RC slab with drop panels. I noticed that when I specify the CS Span Detailer as none, Concept is telling me to use a lot fewer top bars than if I were to specify the CS Span Detailer as code. This doesn't make sense to me since detailing should be about the bar length, not the number of bars. In addition, the number of bars Concept is telling me to use is lower than what it should be if you do a hand calc based on the strip moment.
Can someone enlighten me?
CS Span Detailer as none:
CS Span Detailer as code:
There are some cost factors under Criteria - Calc Options that influence the program designer to select continuous bars vs segmented bars that could also be playing a factor. But ultimately, if you want to control the reinforcement more specifically, I suggest that you use user defined reinforcement. If you want to send the file we can check for anything else at play. Use the secure file upload link or attach it directly as a .zip file if it's small.
