Dear All,

Upon checking the last analysis run log on ETABS, and supposed that you've got GLOBAL FORCE BALANCE RELATIVE ERRORS that is more than the value of zero, is there a way to fix those errors and how?

Thanks,

Hi d3rd,
It's impossible that you get zero results since the program rounds numbers during equations solving. You have to check that any of the relative errors are low, I read 1% or less is good enough. In the case one of those values is more than the limit then you really need to check how to correct it. Check this site to understand better the meaning of this numbers:
