I am working on a linear static analysis of a part(as shown in attached pdf) which is attached to concrete wall with 8 hilti anchor bolts. I am trying to find out the shear and tensile load acting on the anchor bolt due to load(as shown in pdf). When I use the foundation bolt, then the results I got on shear and axial load is shown on the attached pdf which is definitely incorrect. I am trying to understand what am I doing wrong.
I could use the other approach where I create a split surface to represent the washer and then set a fixed face constraint on that and eventually find the reaction load on that fixed face. But then I run into problems of stress singularities during mesh refinement. Also when the option of foundation bolt is there, there should be no need of alternate approach.
