High distortion in bolt shank for some bolts only !!!
Hello, i am having a very strange problem in the shown beam to column connection. 4 bolts are misbehaving giving high distortion. all other bolts are giving proper results. the model is not running unless these 4 bolts are removed. i tried remodeling these 4 bolts, i am getting the same problem.
any ideas what might be the reasons. thanks in advance
