I am modeling a one-way concrete slab. PT girders are in perimeter and in the north-south direction, and mild reinforced infill concrete beam in the east-west direction. When I checked mild reinforced concrete design, I noticed the cross-section at end…

I am working on a life science project with mild slab flat plate construction. My criteria is 8000mips over all and interior bays with 4000mips in certain locations. I am running the analysis with 125 steps/min and 2% damping. I want to know what the…

I am seeing excess temperature and shrinkage reinforcement. The criteria that's being displayed is Det/7.12. In the circled area the middle strip width is 10'. Per 7.12, for a 10" slab, I would need 10*12*10*0.0018= 2.16 in^2. The user input reinforcement…

Given the layout of strips, in odd configurations due to irregular structural geometries, is it in y'all's opinion reasonable to review the original strips for any code-related failures (i.e. shear or tension) and make the proper adjustments to the PT…

I have a slab connected by dowels. What properties in the dowel mimicking slab element do i need to reduce to 0.001 to mimic DSDQ dowels please. I have modelled 50mm x 50mm x 50mm dowels in concrete and need to change kFs/kFr/kMrs etc

Hello Everyone Which is better to intersect the primary beam and secondary beam (Figure1), or Merge the primary beam to be one (Figure2)?

Hello Everyone For a while, I was using an Advanced Concrete Design (RCDC) for the design of a solid slab. Today I tried to learn the RAM concept for the slab designs but I saw a design of strips that had never seen before (When I was using RCDC and…

How do I change Mton/Cm to Kn/m

Dears, Concerning the design of RC beams in a PT slab, i am trying to determine the most accurate way to design the beams (determining top and bottom reinforcement). in Ram concept all design procedure is based on design section analysis. i prefer designing…

I have an existing two-way slab that I am trying to analyze. At locations of negative bending, the effective depth for one way shear calculations is much smaller than I'm calculating it to be by hand. Based on the value that the audit is showing, it…

I have got my report, but there is no loading details like dead load, Wind loads and all... In report settings i have added Loadings, but its not showing.... Wt to do???? i want to see other load details. How to get that details?

Is it at all feasible to design regular column and wall footing in RAM concept? Thanks, S. Bouvia

So from reading the RAM Concept Load History Calc Options Technote it appears that the shrinkage restraint will just adjust the cracking values of the concrete floor for long term load history calculations is this correct? For instance if I have a floor…

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…

Under Criteria and Calc Options in RAM Concept V4.1.1 there is an option to select the matrix solver as either Paradiso or Skyline. Where can I get more information as to what these solvers are doing? Also we have a pretty large model and would like to…

When looking at the long term deflections in RAM Concept, not using the Long Term Load History calculations. I check the Service Design rule set and under Section analysis, I check the selector called Long Term Deflection, This appears to take the elastic…

Hello. I have a 2-way flat slab with a banded/uniform PT layout. Around my elevator and stair openings, we have beams framing the openings. My question is in regards to failures resulting from higher than expected values of torsion in these beams …

Hi, This is my first post in this forum. I'm currently working for a post-tension consultant in Australia. I have some questions regarding Ram Concept and post-tension long-term losses According to Ram Concept manual the long-term losses includes…

What does this audit text mean: “Depth “d” is zero - replacing with “column” effective depth. Depth is still zero - giving up.”? As noted in the Bentley technote, this condition can occur at the inflection points of the slab, which causes the slab…
