Overlap location in the columns and shear walls
Overlap location in the columns and shear walls
(OP)
Dear All,
In the prepared shop drawings for steel reinforcement by supplier he did the following:
for columns, overlap in the middle of column
while in shear walls overlap at the bottom of verticals
The Slab is PT,
I do understand the for both columns and shear walls the zero moment will be at center, so why both have different overlap location.
The Tower is 60 Floors height
regards

RE: Overlap location in the columns and shear walls
In some seismic regimes, splices in columns resisting lateral displacement are located at or near column mid-height in order to avoid the high moment regions as you've suggested. Might that be the case for your project?
Lastly, note that the vertical rebar in most tall shear walls is governed by cantilever flexure of those walls over the entire building height. As such, there really is no zero moment condition at each floor in general.
I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.
