There was also some work done by Kelly and Chalhoub at Berkeley in 85,
86, or 87; as well as some studies based on documented damage in the 1983
Coalinga Earthquake.  The reports, 35 mm slides, etc. were available at
the UC Berkeley Earthquake Engineering Research Center  (EERC) library: or email at eerclib(--nospam--at) or
