Shear Wall Results
Shear Wall Results
(OP)
Hi ETABS USERs,
1.0 When we assign shear wall as pier or spandrel, then we let ETABS design the shear wall, in the output for the pier gives shear reinforcement, it gives shear value say 4022 sq mm, wall thickness is 600 mm, shall we divide the area by 2 (2011 sq mm, 16mm dia @ 100 o/c each face) or put all the 4022 sq mm in each face, say 16 mm dia @ 50 mm o/c.
2. Where can we find in etabs help or manual the distribution of shear wall rebars results to sustantiate item 1?
Thanks,

Yes that could be one option, but I just want to use results given by etabs for prelim. Refering to the original question, what shall we do?
Thank you,

RE: Shear Wall Results
1a) Pier design: The shear reinforcement reported in the design is total reinforcement (for wall, it is total horizontal steel).
1b) Spandrel design: The shear reinforcement reported in the design is total reinforcement (for wall beam/beam, it is total vertical steel,i.e., shear links).
2) It should be there in shear wall design document, ETABS manual
Hope this helps
Cheers

Thank you so much for your reply.
It is a big help!

RE: Shear Wall Results
Does ETABS calculate the shear reinforcing in piers as straight bars or as hooked bars (open or closed)? I couldn't find this information in any ETABS manual or technical notes.
My concern is that if ETABS requires a large amount of shear reinforcing in piers, I don't want to specify large bars (#6 or higher) that would be more difficult and more expensive to bend. So I'd prefer to keep shear bars at #5 or smaller.
However, if ETABS assumes shear bars to be straight, then I'd specify larger bars with greater spacing.
I hope someone out there knows. Thanks.

It is up to you to detail the shear reinforcing required by properly anchoring it in the compression zone.
