Hi, I wanted to see what everyone's preferred workflow is in RAM SS for extracting the moment reactions for each beam in a moment frame to add to your documentation? To my knowledge I don't think there is a report available to give the max/ min moments…

Hi - I was hoping that someone would have some further information on how RAM Frame calculates the seismic stability coefficient (theta). When I do a quick hand check of the numbers given in the report, I find that the reported thetas are significantly…

G'day, If you define a Response Spectra (Custom or Code) with a rotated axes do the eccentricities get similarly translated, perhaps rotated about the COM? I seeking to confirm that I am offsetting the mass by 0.1b perpendicular to the direction of…

I originally modeled my building with flat steel since I was not sure how we would slope the steel for roof drainage. We have determined the slope so I went back into the modeler and adjusted top of columns and story heights to match my building. When…

I am working on a 10 story concrete building with multiple slab thicknesses on each level (8"to10"). After meshing I receive a very distorted shell element found on diaphragm at one or more levels error. The software then runs the analysis but it cancels…

I'm trying to validate the ELF analysis in Ram but ran into an issue. The applied story forces appear to be calculated correctly but when it get's converted into a building story shear the forces not only get amplified in some situations, they actually…

I understand that RAM automatically prevents a code check on certain shapes that are often intended on being for tension-only. https://communities.bentley.com/products/ram-staad/w/structural_analysis_and_design__wiki/3058/ram-frame---tension-only-faq…

I am looking at the requirements of the beam at the second story of the chevron BRBF. Why is RAM Frame checking Beam ductility using the Diagonal Brace requirements of AISC 341-16? The output clearly says it does not check the axial demand in the beam…

In RAM SS, how does the program distributes the lateral load (seismic and wind) in a rigid and non-rigid diaphragm? What are the differences in outcome with the different diaphragm types specified? My problem: In the picture below, I am showing a…

I am running the seismic analysis for a 3 story structure and have questions about how to determine the appropriate building period to use for the seismic analysis. Gravity system is typical steel frame, with composite slab/framing at 2nd and 3rd Floors…

Hello, The moment in my frame does not seem to be correctly transferring to the fixed ends of the steel beams. All of the moment connections are set to a fixity of "XXX" and are lateral members. The ends do have moment values but seem to be way smaller…

The building that I am tasked to design has a steel framing to resist gravity loading. However, it has infill CMU walls acting as shear walls to take the lateral loads. I am only interested in getting the shear distribution to the lateral walls and not…

Hello, In RAM Frame when running the joint check for Seismic Provisions, I get these errors associated with the joints of my OCBF frames with HSS braces, HSS columns, and wide flange beams. Is this just saying that RAM won't do a code check for these…

To Whom May Concern, I recently update to Ram SS verison 17.02.01.23 SES from 17.01. When I review the model created under the older version Ram SS, under Ram frame the icon for joint code check is disable. However, the joint code check report…

In Ram Structural System is it possible to use the slab diaphragm as the frame element used to resist lateral load? For example, in a concrete garage, is there a way to analyze the large ramps as braces and use the flat slab similar to a moment frame…

I receive an error message "Polygon intersection algorithm failed for the following input polygons:...." when I open RAM Frame. Once I click "OK", the RAM Frame module closes. I don't understand why I'm receiving this error. The only change I made in…

I was evaluating the effect of adding an additional brace to a building when I got pretty alarming results between the 2 analysis runs. It seems like between the analysis runs the story shear forces have almost doubled. I looked to see if I had checked…

Hi. I have a steel framed building with a basement condition where braced frames continue to foundation (one level below grade). I don't want lateral loads to go to the rigid diaphragm at grade level as I don't have a reliable load path, so I have disconnected…

Hello Everyone Please share with me the tutorials about a combined footings

Hi, When rebuilding Mesh data in Ram Frame, I get the following warning: Deck Properties for some elements on story... see image below I have gone thru the modeler but could not find any location on the diaphragm where deck was not assigned. The diaphragm…

I have a 2 story building where the lower portion of the floor plan must cantilever out due to existing conditions. I modeled the cantilever using a combination of gravity extensions and stubs as shown in the floor plans. When I run RAM SS and go through…

I have a system of "Other" walls that I'd like to pull line load reactions from. What is the difference between DL1 and DL2/ LL1 and LL2?

I am trying to analyze a building with CMU and CFMF shear walls. The diaphragm is a metal deck with 3" of concrete supported by CFMF floor trusses. I understand that RAM SS does not design CMU and CFMF shear walls but is there a way I could at least get…

I am working on a building where I need to pull out loads from cross bracing members (tension only). Sometimes the information for braces that are part of the same designated frame number at the same floor does not appear immediately before or after its…

Does the Story Mass Data in the Criteria, Mass and Exposure data report include the mass of the foundation slab?
