How to design rc-structures with hollow core slabs.
(OP)
Hi all,
I want to design 4 storey structure comprised of RC Column-Beam where some part of floor slabs will be used as hollow core slabs (to serve as sound-isolator).
The system for such a stucture could be easily created even using template, but the problem arises when determining how should I model hollow core slab supporting beams. In my idea ,there aare the 2 alternatives that I need to follow.
1. Modeling structure conventinally (assigning the loads which regulations oblige us to do ) as if there won't be used hollow core slabs. But practically I'll use the hollow core slab.
Or
2.Leaving the openings where hollow core slabs will be placed and assigning the beams (with nibs) line loads equal to those which will hollow core slabs will apply.
I don't know which alternative represent the real situation. I'll try either of it.
Thanks In Advance.

Do hollow core slabs really help with sound isolation?
RE: How to design rc-structures with hollow core slabs.
yes you right but I thought it'd be better to ask a form before starting the design. Obvisously I try either of alternatives but the main idea behing posting in this thread was to query whether there any specifications in regulations about the design criteria.
->Do hollow core slabs really help with sound isolation?
Yes they are indeed. So even now on our on-going project we use it in moscow for cinema center sound insulaton.
best regards.

Along the mass of concrete the gaps are also governing the sound insulation property.

Get some documentation from the manufacturer on that sound insulation they should be able to back up the sales claims with evidence.
