I have 16" concrete shear walls, 14 stories tall. The building is not in a high siesmic region, although we are designing the walls with boundry elements. I have gone through and applied reinforcemtn manually, including the specified boundry regions, the corners of the shear walls. When I go into the view/update dialog>boundary elements>tie/link design...it lists the specified ties and spacing where I specified the boundary elements to be along with spacing below maximum. Although in the boundary elements>extents tab I am not getting any extent evaluations for my section cuts...and I get design warnings along with that, saying "Layeral ties are required to confine vert reinf per 14.3.6" and "max spacing of vert ties per 126.96.36.199". I get these warnings for all of my horizontal section cuts. What is causing these warnings?
