Punching Shear
Punching Shear
(OP)
hello everyone
Can anyone tell me a book that explains the technics for strengthening slabs to punching shear.
I have a problem of punching and I can't find nothing about it.
Thank You very much

If so, column collars, caps or steel sections adequately fastened to the u/s of the existing slab has been done before.
Column enlargement is also a possibility. But more expensive than caps or collars. If steel sections are installed to the u/s of the slab, you would need to check fire rating issues.
External PT will also work depending on the slab arrangement/geometry, but typically will only be economic in existing slab strengtening applications if other deficiencies are present (eg flexural and/or deflection problems too).
Re books about punching shear strengthening....not much out there, but a paper my Pete Popovic from WJE (Chicago) covers concrete shear collars....let me know if you are interested and I will try and get you a copy.
ACI Manual of Concrete Practice (5 volume set or CD) has a document on slab strengthening that I think covers punching shear strengthening to existing slab.
