Design criteria of column and wall
Design criteria of column and wall
(OP)
Hi all'
i m confused about the design criteria of column and wall. ACI 318-11 code describe, for special moment resisting structural member which axial force is greater than (Agf'c)/10 must be design as column i,e least dimension to long dimension ratio should be within 2.5 and minimum dimension should be 12 in. But in another section they distinguish column and wall design as width to length ratio i,e if ratio is less than 2.5 than column on the other hand if ratio is greater than 6 than member should be design as wall. now my question is if we have any member for architectural requirement width to length ratio greater than 6, minimum dimension 10" but axial force is greater than Agf'c/10. what should we do in this situation.
Thanks

I would think that your length to width ratio kicks you into behavior like special structural walls. Unfortunately this means that you now have a dual seismic system and you need to re-evaluate your seismic force calculations, or you may be able to eliminate that wall from the force system and skirt around the seismic detailing requirements. I hope this helps and I am sorry if I missed something that makes this just a high sounding tangent.
