Hello Team,
In RAM connection stand alone as well as the in-built connection design tab of STAAD Pro, the interaction check of anchors in base plate design considers maximum demands which are from different load combinations. Should the interaction check not be done for same load combination?
In the snip above, the demands are from different load combinations.
Hello,
Can you please share the connection file with us for a quick check?
Hello Abhisek,
I'm trying to upload the file. But getting an error message while uploading. Can you please suggest an alternative to share the file?
check this please.

I have uploaded the following files in secure upload. Can you please check now?
Thanks, I will check and get back to you.
I can not match the values of the screenshot with the values in the shared file. However, you can check the maximum tension value reported and the load case and match with the value at your end. Though the tensile load is not matching, the anchor will be subjected to some extra axial force due to moment and that calculation is done internally and reported in a table as shown below.
With this I am able to match the value, please try at your end.
hi Abhisek, Thanks for trying out the file. But the snip I posted 1st was for a different calculation in the integrated version (connection design tab of staad pro). Hence the values need not match. But In the connection design file I uploaded now the shear corresponding 57.58kip tension is 6.68kip. This value is not considered for the interaction check. Instead the interaction check considers maximum shear demand load combination. I want to understand why the interaction check is not done for the values of same load combination
As per the above snap, you will find the maximum tension for load case 11 is 57.58kip and for that load case shear value is 26.72 kip.
As the axial force changes due to presence of moment, the net tensile value of one anchor has been considered.
Using these 2 values for load case 11, the interaction has been checked.
HI Abhisek,
The values I see are different. I use RAM Connection Standalone V13 Update 6. Please find below snaps showing interaction ratios for minor(LC5) and major (LC11) axis respectively.
