Extensive equipment is available for conducting field
tests of bridges and other structures outside the structural testing
laboratory. This equipment includes an enclosed trailer outfitted with
a 72 channel high-speed data acquisition system and all necessary instrumentation
and equipment required to perform and collect data for a field test.
Instrumentation includes linear variable differential transformers (LVDT's),
single use and demountable strain transducers, and seismometers in the
vertical and horizontal directions. The test equipment also includes
a drop weight device for impact testing and controlled structure excitation.
