I am trying to run the RAM concrete module for a building that has a partial podium slab at level 5 and a partial podium slab at level 4. I'm currently getting the error below, which is at an exterior other wall that is sitting on a concrete beam at level…

Are the design limitations in this article still valid for ACI318-14 for Sway Frame Columns in RAM Concrete? Have there been any progress on the open defect and enhancement numbers referenced? communities.bentley.com/.../ram-concrete-column---aci-slenderness…

https://communities.bentley.com/products/ram-staad/f/ram-staad-forum/158562/ram-concrete-vs-frame-forces-for-columns-not-matching I understand that the analysis methods are different between the two modules, however the difference in axial gravity…

ASCE 7-10 12.14.8.3.2.1 requires that "The design of structures with diaphragms that are NOT flexible shall include the torsional moment, Mt, resulting from eccentricity between the locations of center of mass and the center of rigidity". I created…

Please see specific questions at the end of this post. As an overview of the issue, I would like some clarification on where the loads in the "Gravity Column Loads" and the Foundation Loads > "Gravity Forces from RAM Concrete" reports within RAM Manager…

In RAM Concrete, I assigned 0.5" as clear cover in Criteria->Beam design tab. However, after the design is run, the beam design results display that the assumed clr. cover = 1.5" for both bottom and side. Can anyone please explain why my defined clr.…

When I design RC beam using the Beams →Concrete module, the Asreq at the critical section changes drastically between 2.83 and 6.29 sq. in. depending on the number of bars I provided. As can be seen in the attached screenshot, the moment capacity is larger…

Hi, When I design concrete columns in RAM Concrete, it uses the cracked factors of the slab and column in RAM Modeler. If I model the slabs with bending cracked factor of 0.25 and column cracked factor of 0.7 per ACI, I get significantly higher moments…

I am working on a concrete structure with a couple of transfer levels. One of the transfer beams that I am using exhibits a shear of around 1400kips in the last 6" of it's span (within the support column). The transfer loads on the column are 105k and…

Hi, I'm building a new RAM SS model and looking at sizing columns in RAM Concrete Column. In 'Edit bar patterns' the bars are prefixed with #, eg #3, #4, #5..., they should be H10, H12 etc. I presume this is pre-set / dictated by the code. I had this…

Hi, I am getting confusing results for an 18x18 column with f'c=5ksi reinforced with 8-#8 (3x1) and #4 ties @ 12" spacing. The column is modeled in two segments: the first segment spans to a mezzanine floor level; the second segment then spans to the…

I am trying to understand why the wall axial load (in a concrete wall) does not more closely match that of the applied load (using 1-way deck). When I "view gravity loads" applied to the wall this matches the tributary load to the wall. This makes sense…

Is the support for the beam assumed to be at the face of the column for beams? Therefore, for a simply supported beam (pinned - pinned) will the max moment be the same as calculating the moment based on the clear span as opposed to centerline to centerline…

If there are gravity walls or gravity columns (any material) on top of a gravity concrete beam will these display in these views/report? Or is it only tributary loads (point and line loads) on that floor? Thank!

Is there a way to look at the column moments for a gravity column in a diagram presented similarly to RAM Frame? I have a gravity column that is assigned as pinned at the base, but my major axis moment doesn't return to 0? Only the minor axis moment returns…

How is RAM using the nomograph to calculate the K factor for a non-sway column that is braced by the slab? Under the "bracing criteria" if I keep the assignment as "slab braces the column" but I don't have a beam framing directly into the column in that…

Upon using this spreadsheet, I noticed the equation for the cracked moment of inertia excluded the term in the equation circled in red. What is the reasoning for this? Also, there is a reduction factor on the "Get Strength" sheet that does not seem to…

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…

When modeling a two way slab is it needed for the beams to be defined as lateral or can I leave them as gravity. I have my concrete columns modeled as lateral since they are transferring onto steel columns. I just want to confirm that all the loads are…

In the Ram Concrete module, When I run the Process > Analyze, it gives me the attached warning message: I assume the warning is referring to the highlighted line that says "Either all Degrees of Freedom Fixed or Internal Error." Does anyone know what…

Greetings All, I am working on a RAM SS model for an existing building and I've come across the condition shown in the image: There is a low concrete slab framing into the bottom of a concrete beam and another concrete slab at a higher elevation…

When opening a STAAD file in RCDC or trying to open the advanced concrete design module through STAAD, I get the error "Unable to read analysis data". I'm using STAAD CE 22.04.00.40 and RCDC CE 09.02.00.32. I've checked that my loading in STAAD has load…

I have 3 levels of a concrete two way slab that gets transferred onto steel as shown in the image below. when I look at RAM concrete column design forces I get an axial load of (379 kip). When I look at the same concrete column in RAM frame the forces…

I have a multi level concrete building modeled in RAM. I used RAM Concept to design the post tension slabs, but now now one of the levels is not properly updating in RAM Concrete. When I go to the "Column Design Forces" in the Concrete module all of the…
