Slab with openings

Slab with openings

I am interested in finding literature on design of reinf. concrete slabs with large openings.

RE: Slab with openings

I do not have litrature on it but I would model with solid and beam elements.

RE: Slab with openings

Try the German book "Platten" by Stiglat and Wippel.

RE: Slab with openings

Section 13.4 of ACI 318 is about openings in 2-way slabs.
You can order ACI318 at their website www.aci-int.net.


RE: Slab with openings

Probably you can use any of the plastic approach to design your slabs with cut-outs.

RE: Slab with openings

Prueba usar un software que se llama SAFE.

RE: Slab with openings

I think Jose is recommending SAFE from CSI Berkeley.

RE: Slab with openings

I would suggest using any FEA software like SAFE or RISA3D. Whatever means you use, be sure to accurately account for the effect of openings near column supports (i.e. reduced punching shear capacity). Since design for punching shear typically assumes that the loads come in from all directions, having an opening within the vicinity of a support will change the load path and thus change the shear behavior over that support.
