can etabs design box shaped shear walls?
dear friends, i have a box shaped shear wall in my building and i have faced a problem about designing it. i assigned all 4 walls in one pier and used section designer to model the wall and assign bars to the wall. according to etabs manuals etabs can design u,l,t shaped shear walls but i don't know if etabs can design box shaped shear walls or not. on the other hand, should i assign my shear wall with a combination of a u shape and a single wall or i can simply assign all 4 walls in one single pier and design it with one section defined in section designer. your help is highly appreciated.
(note: i have an openings in one of the walls but its size is negligible comparing to the size of the shear wall.)
