I have an 8"x16" concrete beam and in the end span of a multi-span condition, it says the bottom flexural beam reinforcement fails code limit by 1 bar. I have 2-#5 bars currently for all spans and for every other span, this is adequate and meets all code…

i have done the rcdc, column and slab but when comes to beam are shown the beam lines is missing

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…

I analyze my model using ram structural system and design the shear wall using ram concrete but I found out that my shear wall located at transfer level have exceptionally high shear force.

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…

RAM Concrete crashes (just closes out) when it gets to the final steps. The model never had an issue before. Has anybody ever come across this? Can I upload my model?

Hello! I wish to design a mat slab supported on timber piles in RAM Concept. Would anyone suggest the right way of modeling this in RAM concept and also the properties that would be idea to assume for timber piles? Thank you!

I am getting the me ssage "attempted an unsupported operation" while accessing the design checks tab in the beam design criteria. What does this mean?

I am running a model in the Ram SS Concrete module and getting a few errors with the moment magnification factor exceeding 1.4. When I attempt to back-calculate the results the program is getting, I am not getting the same numbers. So my question here…

Hello, I am currently working on a concrete building with the lateral load resisting system being composed of coupled shear walls. I have been using RAM SS Concrete to design the rebar so far. There are doorway openings in some of the walls and I will…

I would like to get member column/beam forces using RAMDataAccess. The force that I'm referring to can be obtained from following: RAM Manager > RAM Concrete > Process > Results > Member Forces. From here, I can select load cases and forces ie. axial…

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.…

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…

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…

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…

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…

Hello again, I'm having some issues with the integration of RAM and RCDC. I am using the NBC of India. Is Live Load Reduction meant to be applied in RAM to the reactions? It does not appear to be incorporated in the reactions. It appears that…

Hello, I am using RCDC Advanced Concrete after using RAM for the analysis. I have imported the beam info from RAM after running RAM Frame and RAM Concrete analyses. I am having issues with the V(D+L) and Vu-sway calculation from Skip Positive and…

How to activate the special concrete wall feature in Ram E.? How to add special boundary and end flanges to a concrete wall in RAM Concrete? Regards.. Hazim

I have been doing some extensive reading on these forums and in the help but still don't have clarity, so please help me with a few questions: I am modeling a 4 story reinforced concrete moment frame in RAM and then will export the model to RCDC (Advanced…
