Re: precast flat slabs

Dear Andrew,
I am familiar with hollow core panels ,  I had been consulting to "Spancrete Israel" for a few years.
Thanks for your respond , but I am looking for a reference on prestressed flat planks .
regards,

Are these pre-stressed hollow-core type panels? Is a manufacturer chosen? Are they made in Israel, so that you can get information directly from them? Typically in the US these are propietary products with varying engineering properties depending on the exact manufacturer, and each type of panel will give you different loading capacities. Things to know are panel thickness, topping slab and thickness, and the spans. Then they should provide you tables for superimposed loads as well as point loads and other situations. Here we supply the loading and select a type of panel from their tables, and on our drawings these are a pre-engineered product. They supply us with product layouts and calculations signed and sealed...
 
I have some typical tables and info I could email at the office on Monday, probably stuff you can find on the internet as well...
