is a book available through Amazon by Prof. Charles Dowding that covers a large
number of types of damage from vibrations. I don't recall if slabs were
covered (and the book is at home right now) but he has good clear discussions on
what to look for to evaluate same.
However, in my experience, slab cracking in residential
construction is usually related to temperature, shrinkage, direct vertical
loads or settlement. The only case I can think of where
vibration might be the proximate cause would be a slab on grade built on loose
sand that was subsequently densified by vibration.
then my experience has been in Northern California, so take it for what is's

Do any of you have information or references that
would indicate the threshold for peak particle velocity from remote
sources such as blasting, seismic or heavy construction equipment that
would begin to cause cracking in concrete floor slabs on grade in
residential structures? I have seen papers on damage to dry wall and
plaster from these sources, but nothing on typical 4" concrete floor slabs
that are found in production housing in southern California.
