Hi,
I'm using RAM Concept to do a load run down. I'm trying to use a live load reduction factor in my calculation. This is what I've done below accordance to FAQ but the results reaction still doesn't provide any live load reduction to me.
I've…
Hi RAM Support,
I am working on a project and we are thinking about using RAMDataAccess to retrieve all gravity and lateral column gravity forces for foundation design. We would like the force to be retrieved like "Load Summary" in RAMSteelColumn module…
Like it says above, design of beams takes at least 20 minutes every time. But if i jump onto another computer and run the same model, it takes 8 seconds. I'm running a AMD Radeon RX 5700 XT. I've updated my drivers, and changed monitors to no avail. Does…
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…
RAM Structural System CONNECT Edition Version 17.03 SES Release Notes
Release Date: January 27, 2022
This document contains important information regarding changes to the RAM Structural System. It is important that all users are aware of these changes…
I am designing a PT parking garage that starts in structural system and uses concept to design the floor plates. I have ramps created as intermediate levels that make the column lengths in concept too short which affects the stiffness and hyperstatic…

I am analyzing a floor using RAM Concept and I tried adding point spring supports under beams... However, when I try to run the vibration analysis, I get an error saying "An error has occurred while solving the Eigenvalue problem"
Hi Guys, My building period is greater than the Ts value and per ASCE7-16, 11.4.8 the code based response spectra has to be adjusted (penalized). RAM does not adjust the spectra? is there a way we can incorporate it. I am running preliminary analysis…
I have a flat plate, PT building that we have designed using concept and has already been constructed. Now the owner wants to change the residential penthouse to a nightclub which of course the floor is not designed for. I need to pull out design values…
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
Hi,
I am new to RAM Connection and wanted to do the moment connection in CHS sections in one of my project. Can I know whether the connection is available now? If so, which version should I install for the same? ( Circular Hollow Section column and…

I am attempting to assign and design gusset plate connections using Ram connection using data from a RSS model.
When trying to assign a connection detail to a joint the error The joint composed by node "171" and members "120, 886" is not valid "Column…
Are you working on concrete structures and want to see how you could be more efficient with your analytical tools? Here is a great blog and webinar series for structural engineers focused on reinforced and post-tensioned concrete design is now available…
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…
I'm modeling a very simple 10" roof slab with some long-ish cantilevers (22" from edge of slab to face of wall).
For some reason, the Concept module of my RSS model insists on putting 6" or 12" anchored rebar around most of the slab's perimeter, top…
See the attached image. I am wondering if there is a way I can use one large plate to connect all of the braces and the beam to the column, using bolts into the large gusset that is shop welded to the column. Can I replicate this in RAM? if so, how? Thanks…
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…
Are there plans to include ACI 318-19 provisions in any upcoming releases for the RAM programs? If so, is there an ETA on this? Our AHJ will be adopting IBC 2021 in a few months, but we need to have the ability to start designing concrete structures in…
As the title implies, it would be helpful if dialog boxes within RAM Concept had a "Help" button that takes you to the section of the help file describing the various settings in the dialog box. This feature is already present in RAM SS, and it would…
Hello all,
I am looking for the latest version of RAM SBeam. Is it RAM SBeam v 7.0? Also, if anyone can include a link for the download, thank you.
By the way, I wasn't sure if this forum is the proper location to post this question for SBeam. Moderators…
Hi, I'm working on a mild reinforced slab and it seems to be working fine, however im getting a warning that says some of my rebar is out of seciton. I already checked and the user defined rebar is within the trimmed section, i looked at the Cross Sections…
