This is the web site which descibes the former Fast Hybrid Testing
laboratory (FHT), located at the University of Colorado in Boulder which was for five years
a node of the George E. Brown, Jr. Network for Earthquake Engineering
Many information are by now obsolete, but are kept for reference.
Questions pertaining to the FHT, or the tests subsequently performed by Saouma, or about Mercury, should be directly addressed to saouma at colorado edu
. The FHT laboratory is open for use as a national
laboratory for researchers and for contract testing by private companies across
the country who are interested in conducting real-time (or pseudo-dynamic)
hybrid simulations of structures subjected to earthquakes, wind, and other
The FHT laboratory specializes in
real-time hybrid simulations. In this innovative simulation paradigm a
substructure is physically tested in the laboratory floor while a
complementary one is numerically analyzed by a finite element. Both simulations
are tightly coupled and run at increments of 1/1,024 of a second. The
FHT laboratory includes extensive computational and archiving facilities, and
the laboratory supports interactive remote teleparticipation of experimental
Take a look at our current project!
