When checking the reaction forces I found that there were a few points numbered as negative (like -100) by ETABS, and more wired was that I got force reported at these negative points, the total force including these negative points was balanced with applied loads. However, no such negative points were reported from building model! No coordinates were associated with these negative points so that I couldn't track down them. Anybody has this problem before? I had 3 different building models and 2 out of 3 have the negative point number problem. How can I get rid of this negative point numbering? Thanks

ok, the problem is solved. the negative point numbering comes after the auto mesh of the wall as ETABS adds a restraint to the mid-node by default.
