RAM Frame crashes when initializing

Andrew Yu — Thu, 25 Aug 2022 18:16:54 GMT

RAM Frame crashes after opening and reaching 50% during initialization. It was able to open perfectly fine at some point. I went back and added more surface and line loads. Now it crashes. What would be the fix for this?

RAM Concrete crashes at the final step

Andrew Yu — Mon, 22 Aug 2022 21:08:01 GMT

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?

RAM Concept - Strip and Section Analysis

Andrew Yu — Tue, 17 May 2022 18:05:40 GMT

Can a feature be added to RAM Concept for Strip and Section Analysis plots that allows us to chose the points to be plotted along with the diagram?

For example, showing shear values at a specific location rather than just the peak shear demand at face of support. Shear demand for design is based on shear at d away from support. I would like to be able to see this on the plan. It would also be helpful to have the shear values at other points, so that we can determine if we can reduce shear reinforcing further down the span.

RAM Concept - Strip and Section Analysis

Is there any way to make the diagrams display more points for the demand? In particular for shear... I'm interested in getting the shear demand at a certain distance away. Currently, I have to make length measurements and scale it to find the shear...

If not, can this feature be added? A setting that allows users to choose how many points to display similar to how RAM Frame allows you to.

RAM Structural System & RAM Concept column moments differ

Andrew Yu — Wed, 28 Apr 2021 17:59:59 GMT

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 in the column than in the RAM Concept model (assuming this is a single floor model).

I am modeling the slab in RAM Concept without crack factors (default 2-way slab). Is this the reason why the column moments in RAM Concept are so much smaller? Should we be putting the crack factors for the slab in RAM Concept?

Does the strength design of the slab in RAM Concept account for load history cracking? Are load histories only used for deflections?

Thanks,

Andrew

RAM Concrete Column Design Loads

Andrew Yu — Fri, 19 Jun 2020 15:22:42 GMT

I'm designing concrete columns in the RAM Concrete module and the slenderness amplification seems excessive for 1 of the levels. The column demand and design forces are in the images below. Is there something wrong with the calculation or the modeling? It doesn't make sense that the minor moment which is seemingly non-existent should be amplified by 41 times. Has anybody encountered this and is there a fix?

Thanks you.

RAM Frame Internal FEA Error

Andrew Yu — Mon, 11 May 2020 15:51:53 GMT

I had a working RAM Structural model which had a saved RSA result. I tried to run it again with Equivalent Lateral Force load case, but I'm getting an error saying that there are "invalid node ID" and that "Internal FEA Error. If this Message Generated During Analysis, Check Your Model for its Validity, Otherwise, Contact Bentley Technical Support." I haven't changed anything in the model, so I don't understand what the issue is.

Does anybody know the fix to this?

RAM Frame - RSA Load Cases combined with Gravity Load Cases

Andrew Yu — Sat, 14 Mar 2020 00:31:38 GMT

Whenever I try to run the RSA load cases with the gravity load cases (dead, live, etc), the analysis gets to "evaluating/storing member forces" and crashes. RAM Frame closes and saves nothing. I tried running the RSA load cases alone and there aren't any problems.

What can I do to fix this?

Thanks,
