shearwall boundary element
shearwall boundary element
(OP)
Hi:
For seismic design, ACI requires boundary elements when the stress exceeding 0.2f'c.
If this is one piece wall, the boundary element location is at each end. If this is a T or box type lay out, do you consider this provision apply to the intersection of perpendicular walls?
I would think this applies. Any opnion on this?
Thanks.

RE: shearwall boundary element
If the stresses exceeds the limit even after accounting for the area of the flanges, the boundary element shall include the effective flange width in compression and shall extend at least 12 inches into the web. See 21.7.6.4(b)
