Dear deadlord (post#111)
according to ATKINS ETABS Analysis Manual, if you see 8.1.2 "Global Force Balance" it states thats "These errors are calculated bases on the relative difference in applied external loads and the base reactions for each load case. The global force balance relative errors should be very small in order of 10e-10 and less. It should be noted that this is a necessary but not sufficient condition to ensure a sound modelling and analysis"
1-these errors should be of small magnitude 10e10 & smaller
2-this check must be satisfied for sound modelling PLUS ALL OTHER CHECKS.
