I am working through the column design and I have isolated just one load combination to try and verify some results I see for the slenderness issues I am having. I am not, however, able to verify the Cm value. I know that was suppose to be a bug that…

Hi, I am getting confusing results for an 18x18 column with f'c=5ksi reinforced with 8-#8 (3x1) and #4 ties @ 12" spacing. The column is modeled in two segments: the first segment spans to a mezzanine floor level; the second segment then spans to the…

How does RAM calculate k factors for columns? My calculations for some columns do not match the output. What criteria does it use to determine which beams are framing into the connection? Can you modify the criteria? -Are beams that frame in…

Does anyone know if/how you can model bundles of rebar in RAM Structural System? Currently I'm only seeing the equal spacing method for placing rebar within the concrete columns, but this is overly conservative when considering the bending stress in the…

I am just trying to get some opinions on what is done with RAM Structural System and RAM Concrete Column Design. Currently in ACI 318-08 there are three methods for column design. sections 10.10.3, 10.10.4 and 10.10.5, Nonlinear second-order analysis…

When we have circular columns and I assign them to have spiral reinforcement I keep getting the following design warning; Story 5: Minimum shear spacing limit is greater than maximum limit Story 4: Minimum shear spacing limit is greater than…

I was wondering if RAM SS in either RAM Concrete or RAM Frame can calculate the stability index as noted in ACI 318-08 equation 10-10? If the program cannot calculate the stability index is their a procedure of how to get the variables that are required…
