MpM, MpN, Mstrip are calculated in RAM connection
MpM, MpN, Mstrip are calculated in RAM connection
(OP)
Dear engineers,
I'm checking the calculation for anchor bolt base plate connection. My client has sent me this calculation generated by RAM Connection. But there is no formulas shown in it.
RAM Connection directly gives the value. Not the formula.
How MpM, MpN, Mstrip are calculated in RAM connection?
Can any one help in this.
Thanks in advance
MpM: Plate bending moment per unit width at bearing interface for the cantilever m
MpN: Plate bending moment per unit width at bearing interface for the cantilever n
Mstrip: Maximum bending moment at the strip

Just be aware that this tends to turn a 3-4 page calc into a 10 page calc.

Second, I have never used RAM connection, however if my memory serves me right, I believe RAM connection allows for two ways to report the connection design. One with straight checks that say the limit state is OK (bolt shear, bolt bearing, block shear etc). The second allows you to print out all of the equations used in the connection check. Ask the person who sent you the connection design to expand this portion of the calculation.
Third, if you are not satisfied with the calculations, send them back and asking for clarification in this area.
Hopefully this will help you a little bit.

The report is with show formula option. But For MpM, MpN, Mstrip No formulas provided. Direct values given.
Refer attached Sample
@SteelPE
I didn't attached anything with my previous post. Please if you can help me provide formula to calculate.
MpM: Plate bending moment per unit width at bearing interface for the cantilever m
MpN: Plate bending moment per unit width at bearing interface for the cantilever n
Mstrip: Maximum bending moment at the strip
RE: MpM, MpN, Mstrip are calculated in RAM connection
I have never used the program however, the terms M and N are oddly familiar to the terms used for bending in the two different directions of a base plate. Check the bearing capacity under base plate and then calculated the moment according to the cantilever M and N (attached) and see if you get the same answer.
This shouldn't be too difficult.

Are you sure you should be using this program?
RE: MpM, MpN, Mstrip are calculated in RAM connection
I want to know how to calculate MpM, MpN, Mstrip from the applied load. AISC DG 1 does not give any clear idea about it. Please refer the attachment to understand the issue.
RE: MpM, MpN, Mstrip are calculated in RAM connection
If you still can't get the same answer as the program then you should either call RAM for an explanation or stop using the program.
RE: MpM, MpN, Mstrip are calculated in RAM connection
I would ask the design engineer to provide you with the info you request. If he/she did the calc they should know.

JUST EXAMPLE I USED THAT SHEAR AND MOMENT VALUES.
PLEASE SEE THE ATTACHED OUTPUT.
THERE IS NO FORMULA SHOWN FOR MpM, MpN, Mstrip, i (Weld MOI)
If anyone familiar with these type of design please provide the formulas

I think your needle is stuck in a groove.
I would ask the Engineer that submitted it to you to provide. At least they are going to be required to send the calc, here we are not, and asking the same question over and over will not help your cause.
