Hello,
I am lloking to write a finite element code for the analysis of voided slabs (also known bubble deck slab).

Bubble deck slab is a method of virtually eliminating all
concrete from the middle of a floor slab, which is not performing any
structural function, thereby dramatically reducing structural dead weight. High density
polyethylene
hollow spheres replace the in-effective concrete in the centre of the slab,
thus decreasing the dead weight and increasing the efficiency of the floor. By
introducing the gaps leads to a 30 To 50% lighter slab which reduces the loads
on the columns, walls and foundations, and of course of the entire building.
The advantages are less energy
consumption - both in production, transport and carrying out,
less emission - exhaust gases from production and transport, especially CO2.
The aim of this paper is to discuss about various properties of Bubble deck
slab based on the various studies done abroad.
More information on these voided fllors can be found here

I would like to go about preparing a finite element code to analyze such floor systems.
Can anyone advise how to go about?
