Set fixed composite stud spacing RAM SS in inches rather than quantity.

Hi, I am modelling a beam with a change of deck along the length of the beam (half of the beam has a W2+3.5" verco deck, and the other half has a W2+2" deck). I read this response: Effects of Changing Deck Type - RAM | STAAD | ADINA Wiki - RAM | STAAD…

I have a failing composite W14x22 beam that spans 25ft with an additional 5.25ft cantilever. My controlling moment shows it as controlled by dead load only with a negative moment of 33.7k-ft: The capacity provided (16.46k-ft) is for the entire…

When I model a beam (i.e. W steel) with a plate and a simple beam but distributed equivalent load to that plate, results in end reactions and diagrams are different. Why are happening those differences? I think something is working in the composition…

Hi All, I am trying to model multiple loads along my composite beam. Can I place my loads not on the beam, but between the beams on the slab? I am still very new and not familiar with the software. Thanks!

Hello, I am new to Staad and am unsure how to add spring supports to the top of my structure. I am modeling a simple two column, 1 beam frame with spring supports (absorption pads) that connect the frame to the composite slab above. My question is…

Can we check the composite design using the IS 800:2007 in RAM SS? Is there any alternative or interpolation of design which can be done to this exercise ?

I am new to RAMSS but have used many other design software to design composite beams. RAMSS seems to be giving me design errors and also not following my design conditions for the composite beam design (please see the screenshot below). The high level…

When designing composite steel girders, does RAM Steel Beam consider the self-weight of beams supported by the girder and the line loads on those beams as non-composite loads or post composite loads?

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, Is there an option to view all the composite beams in the model plan view, rather than clicking on each individual beam to check if it is composite/noncomposite? Thank you, Julianna

Hi, If the stud criteria is set to use uniform distribution, how does RAM treat a cantilever? Are the required number of studs assumed to be on the main span only or the full span including the cantilever? For example, a 20 ft main span and 5 ft cant…

Hello, I am wondering how RAM Steel computes the I_{tr} for composite beams. For example, I have a composite beam with the following properties as computed by RAM: But by hand, I am computing I_{tr} = 941.86, slightly less than RAM. I am guessing…

When defining composite beam using Section data base in Staad, what does STAAD assume as dead weight of composite beam? The propery of say W21x83 & MC21x83 are calculated by STAAD and are different in Ax,Ix,Iy,Iz but keeping Ay, Az, D & W same as orginial…

i analise a composite beam using staad.pro select series 1 20.07.06.23, i did de entrance of the beam in the same staad. afer i analyse i receive the next warning " ***WARNING: MEMBER 1 HAS COMPOSITE PROPERTY ASSIGNED TO IT AND HENCE THE MATERIAL…
