Hi,
I have an existing data centre which has never had a raised access floor. The imposed load - 20kN/m sq, has always been applied directly to the floor slab. The floor slab comprises a concrete filled profiled composite metal deck.
The client is changing their cooling strategy and will now be adding a raised access floor. So the same load is still applied, but its now applied to the slab as a series of point loads on a 600mm x 600mm grid.
While the load is the same, so the moments and shear for a 1m strip should be the same in principle, or thereabouts, I’m looking for some degree of comfort regarding point loads on profiled composite slabs.
Has anyone any similar experience?
Thanks
