Concrete module will not allow me to assign a couple beams in a specific wall and seems to be showing the opening to the right of the opening, see below for image when hovering mouse over the pier while trying to assign coupling beams.

I have rigid diaphragms at each level with 8 moment frame beam lines in the Y direction and 4 moment frame beam lines in the X direction. I have Loads and Applied Forces report that shows the diaphragm forces at each level. What is the best way to extract…

We have a mid rise concrete structure that comprises of residential units over a parking garage. Is there a way to differentiate the live load reductions for parking vs residential? If parking garage columns are set to 80% of LL, will the residential…

Hi, When you are designing a moment frame with joists, there's no joint check. Does this mean it doesn't check to see if the column walls fail with connections?

Hi, I am working on a SCCS bridge structure and trying to size columns but for some reason at a few columns results show NG even after filing the criteria. what can be the reason behind it?

Hello, I might have accidently clicked something in my model, because now every time I save my model, saving is a lot slower. When comparing with older versions of my model, the saving seems to slow down for the files ending in .c0, .c1, .c2, .c3. …

Hi, When I am running RAM frame for Tilt up building, and the analysis does not converge because of too low of crack factor, the error window points to a wrong panel. Is there a better way to troubleshoot which panel is giving me an error?

Hi all, I am working with an industrial structure with Pseudo flexible diaphragm. I observed an unusual displacement at couple of places in the diaphragm due to nodal loads (RAM generated nodal loads). I tried disconnecting that node from diaphragm…

Is it possible to add a nodal wind/seismic load in the middle of a beam in RSS modeler? I was in the Modeler and set up wind and seismic load cases and loads, but it seems I can only apply them at the beam ends or column locations. Many of my nodal loads…

When importing a RAM SS file into Concept - does it also important the self weight from RAM SS if it is turned on? I know concept calculates the self weight of the slab/beams automatically - but I am getting significantly higher shear reactions at my…

How can i see or find the local axis of concrete walls? I see wall forces but need to know major axis direction.

I am in the midst of overhauling framing within a large RAM Structural System Model. The model was running without issue prior to updating, but because of architectural changes, much of the framing was recently moved. When trying to run the updated model…

I was importing slab from rss to concept, however, some walls didn't come through and some columns just came in with different properties. How do I fix this? I saved and restart rss a few times already.

Hi, Based on NBCC 2015 4.1.8.11 4) single storey buildings with steel or wood deck as diaphragms can have a higher fundamental period compared to 4.1.8.11 3) as seen in the snap below. However, in the current RAM frame the Ta is only based on clause…

When analyzing a structure in RAM Frame, do the drift results calculated use the ultimate or the service wind load? Also in RAM Frame, do the seismic drift results calculated use an elastic analysis or is the design ratio calculated by multiplying by…

We have created a RAM model from an ISM export from Revit. After cleaning up a multitude of errors associated with the import, we got the model into RAM Frame to analyze for wind loading. When running the model under dead, live, and a user input wind…

Hello, I am having difficulties deleting chevron braces in RAM SS. I am in the process of modifying my model (the roof layout changed therefore I do not need the braces in the long direction) when I noticed I needed to delete the braces shown in the…

When designing a concrete column in SDC D, I noticed that RAM is enforcing the transverse reinforcing spacing requirements from 18.7.5.3 (ACI 318-14). However, when checking induced moments and shears due to lateral displacements in 18.14.3.2, ACI does…

Hi All, I am not seeing the vertical braces (created using special brace option) in elevation mode, so not able to delete or assign a size to those braces. But I can see those braces in 3D view. In data check, there is an error for unassigned brace…

Hi Seth, " Beams in RAM Structural System can only be modeled as I-shapes, HSS (tubes), or channels. It is not possible to model the top chords with any other section, including WT or double angle sections." Is this still the case?. Any work arounds…

The shear check for the anchor rods is showing a value of 5.5 kips for each anchor and since there are 4 anchors on the base plate this equates to 22 kips which is the greatest positive shear from the load combinations. There is however a bigger shear…

Hi All, Is there a way to assign the Make up column (custom size) size to members apart from standard sizes in RAM modeler?. Also, I am looking for ways to input the girder properties. Is there an option in RAM modeler to include customized columns…

Hello, I am running a 7-story steel framed building with flexible diaphragms for all floors. I get the following instability.: I assume I should not run P-Delta with flexible diaphragms so when I turn off P-Delta under Criteria -> General, the instability…
