I'm designing a mat foundation for a 25 story concrete building around the shear walls and I am not sure how to model rock anchors. I've tried putting point supports and columns in the mesh, but those also take compression. Is there a way to make them tension-only?
I remember reading somewhere that composite beams require at least 25% composite action in order to qualify as composite.
Is this listed in any code specification, and if so, could someone please direct me to it?
Thanks
