went to one of the local indian casinos for the buffer (great price and
good food) and notice that the floor seemed to be springy. It's an all
concrete building and I was trying to explain to my friend that it
shouldn't be that way but she insisted that it was to help resist
earthquake damage.

went back and forth so she made me ask around. how do I explain that her
logic is wrong...or is it?

You have no idea if the floor itself (supporting structure and poured slab)
was "springy" or if it was part of the floor surfacing treatment which
created a cushioning effect which you experienced...

true, I have no idea, but I was sitting down at a table and the floor seemed to
spring when people walked near my table. I, rightly or wrongly, eliminated the
idea of a super springy carpet pad



In certain types of flooring a cushioning effect is created by the materials
which are just under the surface layer to prevent injury or fatigue in the
people using the area... Ex: basketball court flooring has shock absorbing
layers underneath the shiny wooden top layer, dance flooring has similar
properties...

Which area of the casino were you in ? In most casinos the "floor" is not
actually the slab, the entire gaming floor area is set up on top of a raised
flooring system of the kind you would see used in a computer data center of
the type you would find a super computer located in so that any configuration
desired for power wiring and communications cabling can be quickly set up
simply by pulling whatever wiring is needed below the flooring system to
whichever spot it is desired or needed in anywhere in the gaming area...

this was the "food court" area which was one floor below the actual casino.
