Base plate with high shear loads.
Base plate with high shear loads.
(OP)
I have a base plate that conects a small stub to a core wall ,the problem is i have a huge shear value, i am considering assuming that the friction between the base plate and the grout will help me in the shear resistance, but the truth is i am not comfortable with this concept, did anyone try this before??
I know design guide 1 approves this criteria but still i am not comfortable?? any ideas???

A sketch might help us to understand your problem better.
I would never rely on friction between two faces, if would put either a shear key or numerous fasteners with a good safety factor and any friction generated would be a bonus in my humble opinion.

If you go with friction, consider specifying an expansive grout such as Sika 212. A little precompression in the grout is good insurance.
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.
