MATHCAD 15.0 Units problem
(OP)
This is my spreadsheet for flat slab design:
The demand and capacity moments moments seemingly have same units( all in ft.kip or ft.lb), however they are not comparable according to the program's error message.
the moment demand is Mu.str_pos is in <ft.kip> uints, while ϕMn.pos seems to be in <ft.kip> in the calculation equation per reinforcement and section geometry. however, if I output ϕMn.pos again, it is in <ft.lb>, and if I use units conversion tool try to change to <ft.kip>, it changed into "sec^/ft*ft.kip.
I highly appreciate your answer.

kip is 1000 lb-force, not lb-mass, which is not how you defined kip and ksi on your reference sheet. When these are corrected by replacing "lb" with "lbf" you get an "ok" for the answer

I was trying to design the negative reinforcement for the slab using the barrier design results( the vehicle impact force and moment etc. from the reference file for barrier design). none of the barrier design results can be carried over and recognized by the slab design sheet. The variables that I was trying to be used are : Lci, Lce, M.cint,M.cend,A.barrier,cgx.barrier.
I have no problem to use the variables defined in the other three reference files.

It is just some variables and results that I actually need to use can not be carried over into my main sheet.

> you switched ORIGIN to 1 in the reference sheet, but ORIGIN=0 in the main sheet
> your Long.Data matrix is not transferring, but hardcoding the matrix does allow it to be transferred, but ORIGIN discrepancy still needs to be fixed

I was sidetracked by some review tasks. I will get back to my spreadsheet again soon. I will let you know.
