shear keys in foundations

shear keys in foundations

(OP)

I'm to design a foundation and the structural engineer shows 200x80x25thk member as shear key inside the plinth, but when I checked the bolts and plinth and foundation for the loadings given to me I see that I don't have to provide the shear key... Is the shear key important to put if the concrete design is fine or I still need to provide it for his steel column ?

RE: shear keys in foundations

Ask the structural engineer, not people on the internet.

RE: shear keys in foundations

Seconded. You can't not include something without a blessing from the engineer. Maybe it's a redundancy in his design.

RE: shear keys in foundations

I've seen "shear keys" installed to inhibit water leakage, similar to a very crude waterstop. I've also seen drafters show them just because they were taught that's what a cold joint is supposed to look like.
