Hi there, I would like to know what is the calculation behind the column flange local bending at the beam top flange in Check 22 for Bolted End plate connection? Is there any email address I can direct RAM connect report for further explanation? Thanks.

RAM incorrect Doubler Plate Report_210713.pdf

Hi Seth,

I've attached the report with the formulas and in Check no. 22, page 6 of the PDF, I've highlighted the fact that RAMCON is using "flange doubler" thickness into calculation of "column flange local bending capacity" at the top flange, even though flange doubler is not provided in the design example. This error results in RAMCON incorrectly calculating the column flange capacity.

Can you please let me know if you agree with this? I have attached PDF report with this email. I am not able attach RAM file as it keeps on giving me the error in uploading. If you have another email address, then I will try sending it to you.

Thanks.

I'm getting somewhat different results in a test model. There must be some setting that is different in your file (something to do with the stiffeners).  If you can send the actual file that's best. If you don't want to post it publicly, use Secure File Upload

Hi Seth,

Would you please let me know when update on this would be available? we use this connection many times in our designs and would be good when it is updated

Thanks.

JB4_Std BMEP (4 bolts) with JB3.pdf

Hi Seth,

Further to the flange doubler thickness, I just want to highlight another thing. The design requirement for this check (no.22) is, minimum of (1.11(phi Mbt), 1.11*(phi Ms)). PhiMs is the design section moment capacity attached to the end plate, as per DG 12, page 61. I have attached a 4-bolt moment end plate with 1mm thick doubler plate as you said.

Let me know if you need further explanation or want me to upload the RAM file.

Hi Seth,

Haven't heard back from you regarding the update ?

Is it available now?

No, not yet. Use the Connection client - update notifications or check Software Downloads periodically. Releases are using a few months apart. 

Hi Seth,

Just wondering if the connection has error in it, RAMCON should notify its customers in the mean time while the update is getting ready. Otherwise, engineers around the world will keep on producing incorrect connection which might lead to a disaster.  RAMCON should not take long time to fix this major error as it is calculating both "Demand" and "Required" capacities incorrectly.

But, by all means, RAMCON should notify its customers asap, I think.
