Hi Team, I am analyzing a G+4 Story steel Building using ASCE 7-16 and AISC 360-16, At Level 1, Level2, and Level 3 there is Concrete Filled Metal Deck which i considered as Rigid for analysis. At Roof Level there is Bare Metal Deck Which i considered…

In RAM Steel Beam, I get Fatal Error for "Illegal Framing Configuration or Missing Slab Edge Detected for a Wall" related to one of the walls of my elevator enclosure. I have deleted the walls and redrawn them; confirming that their nodes match. I have…

As shown in the image above, a project we have has steel beams connected to concrete columns. Based on geometry alone there should be a moment applied to the column during design in the Concrete module. Added to this, the red beam on the left has a gravity…

I have a building with screen wall loads on the roof. These loads act as a couple with the main post and the kicker having reactions in opposite directions. When I add these loads to the ram model, ram beam module is only considering the downward gravity…

In the RAM Steel verification document, I noticed that you're using two different equations for the concrete modulus of elasticity Ec. On page 2, you use the AISC Chapter I equation for stud strength, and on page 5 you use ACI Eqn. 19.2.2.1a for I,effective…

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…

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…

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 aware that RAM SS designates a joist as SP, when the slope is greater than 1/2" rise per 12" span. My question is, for a 2 1/4":12" slope, when the design is given as SP, say 16K4 SP, is the joist designed as 16K4? Or is there any other design I…

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…

I am working on a two story steel building and am experiencing issues with the beam optimization. RAM is currently using a loading combination for some beams, displayed below, that is not the maximum loading so the beams are designed too small. Instead…

I am getting Illegal Framing Configuration Detected on the circled beams below. Not sure how to resolve this. Immediately to the right of these beams is two way slab, not sure if that has anything to do with it. I modelled slab edge using "Whole Perimeter…

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…

Can i manually change the modulus of elasticity used in Ram steel? The client wants us to use E based on the Euro code but design is based on IBC/AISC codes.

Is there any option for specifying composite joists in RSS? The FloorVibe module had the option to use the SJI Composite Joist designations (i.e. ddCJxxx/xxx where dd is depth and xxx are the applicable loads). But I don't see any implementation of that…

Hello, I have a one-story building with sloping parapets on the exterior walls and flat parapets on an interior portion (see white colored parapets in image below). Currently, my model has the floor and the roof, with the roof having the deck and…

Why doesn't the program calculate Cs per equation 12.8-5 ? Cs used is calculated from Eq 12-8-3. If calculated per 12.8-5 the Cs=0.044xSds=0.046 (which is the minimum Cs value to be used) is greater than 0.034.

Why are the Sds, Fa different for the same site class D between ELF and Dynamic load cases ? Please let me know. Thanks!

Hey, I have a composite deck..When I check a particular beam's report I get a 1.4D Mu= 528.6 kip-ft and in the diagrams I can the dead moment 1.4D is 702.07kip-ft. Could you please let me know why the values are different? Please see attached file. Thanks…

We've been using RAM since the 1990's. In the past, I kept our settings consistent from station to station and when we bought new computers by copying the RamIS.ini file from one computer to the next. When we upgraded to all new Windows 10 workstations…

Looking at the reports for a typical composite beam in RAM Structural System, I am seeing that RAM outputs I-effective (Ieff) and I-transformed (Itr) that are different from those listed in AISC Table 3-20 (Lower Bound Elastic Moment of Inertia for Plastic…

Hello , I know there is a way to get the results for frame members from post-processing for each load cases which also includes D and L. Similarly is there a way to get the results for the gravity steel members?

Hey I have a situation where column is outside defined slab edge? What are the implications of this? Please see pic below:

I have a model with 20 stories and most have a unique layout type. However, most of them share a common core of slap openings for elevators, stairs, etc. If I have to make a change on a number of these, I have to manually go and make that same change…

I just go a more recent version of RAM SS and when I run the beam module there are certain beam that now show that they fail in deflection. But when I look at the report the beam does not fail in deflection. I have tried deleting the beam and putting…
