I imported a Mat slab from RAM structural to RAM Concept to help me design the pile caps under the shear walls of my building. When I generate mesh a Analysis error pops up say that there are multiple walls in the same location above the slab (see below…

Hi All, In a Post tensioned slab, I would like to know if RAM Concept can accounts the USER defined Reinforcement to control the deflection and tensile stresses. Assume, I have a stress of 4.5Mpa and I would like to reduce it to 3.0Mpa by defining/adding…

I am running into an issue with the punching shear checks for a slab with drop caps and stud rails. The status plan and punch check audit are reporting that the design fails. However, when I review the punch check audit, the program successfully designs…

Hello, I am analyzing a two-way slab with drop panels and column capitals in RAM Concept and have a few questions per below. - Can you breakdown how RAM concept calculates the min and max moment capacity for ACI 318-14 strength design? The values…

What does the exposure selection in the calc options/load history/exposure "top", "bottom", "top and bottom" affect? Also what is it exposure to? Meaning what condition applies to "top" or "bottom" only? Thanks

How can I get the moment and stress distribution along the length of PT beams in Ram Concept? All I can see are contour plots (2nd screenshot below) but is it possible to get the moment and stress distribution at intervals say every 1 ft along (similar…

I'm using RAM concept to analyze a pan joist system being supported by mild & post-tensioned beams. When looking at the shear reinforcement, the program is providing many more stirrups than expected. The shear demand (Figure 1) shows that the capacity…

Is there a way to check the Φ factor used for shear in mat foundation design in Ram Concept? Since the mat foundation is part of a special SFRS, the Φ-value should be 0.60 if the shear strength of the member is less than the corresponding development…

Dear Officer: When I use RAM Concept Edition V8 Update 4, I already defined a load combo. And when I tried to add "final instantaneous load", the program showed "program error" saying "Program Error (load combos must be defined prior to adding a load…

Hey, I am checking the minimum bearing pressure for the mat slab. I have 500 iterations to run. Still, I see negative minimum pressure. Why I am not getting zero tension at the base of my mat? Thanks.

I have a condition where the beams (& edge of slab) intersect at the column at an angle. They are not aligned with each other and/or with the column face. This is a PT slab and due to the obvious reason, my service condition stress is not working because…

I am getting this warning "Inconsistent tendon half span ratios" in my PT slab model and I am unable to figure out the reason. I tried to look into the manual but didn't find anything helpful to resolve this warning. The inflection point ratio (0.2) is…

Is there a .NET SDK for RAM concept. I would prefer to stick to .NET for scripting purposes as most of the industry are using .NET and we have tooling built around .NET. I can find some guidance on .NET SDKs for other products but can't find any detailed…

I am working on one-way slab supported by mild reinforced concrete beams. The beam is trimmed as a T-section with flange width of 99". I drew #4 at 18" (full slab area) on top of the slab in the direction parallel to the beam, which make 5-#4 (total As…

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 designing a mat slab that will have a single layer of reinforcing. I have followed the advice on the FAQ page, but am getting an error with my design strips that the reinforcement has too much cover. I am trying to center the reinforcement in the…

Does RAM Concept currently account for ACI 318-19 8.6.1.2 for As'min within 1.5h of column face each side? Does it detail two-way non prestressed slabs in this way?

For context working on a 8in PT slab. In the banded direction in my interior bays I have 24 strands (26.8 kip/strand) for a trib width of 29 ft. Thus I have a stress of 230 psi (24'*26.8kip/ft / (28'*12*8")). When I look at Centroid stress plan under…

Hi everyone, I got a question regarding the stress in RAM Concept. Is the Demand stress = actual stress - capacity stress (section capacity) or Demand stress = Actual stress. Notes: Actual stress is stress in section due to loadings and PT action…

Dear Officer: May I ask if RAM Concept can update concrete member stiffness (either from concrete elastic modulus or section modulus) automatically based on the tensile stress results from analysis, which make the analysis kind of a nonlinear analysis…

I would love to create a python script to import loading types and combinations from say an excel spreadsheet. Is that within the realm of possibility? I just wanted to reach out before getting too far into it. Thanks!

I have a slab in RAM Concept and I have input top and bottom reinforcing mats that are well over the required minimum area of steel per ACI 318-14 section 8.6.1.1. When I run my model I am getting some program reinforcing bars added around the edge of…

Hi, I've gone through the initial setup of a Concept model to use the optimizer but am running into the Optimizer runs failing to complete even a single iteration. My initial model was setup with fewer than 50 things to optimize between drapes and tendon…

Hello All, Did anyone ever get this warning in RAM Concept? This happens when I move design strips or modeled elements. See the snip for reference.

I am modeling a hinge on a slab, and I followed the steps on the picture below (which I find in this forum) and the deflection, shear and moments at the hinge are very close to what is expected at the hinge. My question is, can you please clarify the…
