DYNAMIC TESTS AND SYSTEM IDENTIFICATION OF BRIDGES

A five-span, four-hundred-foot long, reinforced concrete box girder bridge supported on single column piers that are pile-founded was subjected to extensive dynamic tests. The pullback and quick-release method of excitation was used. Two D-8 crawler tractors were used to apply total release loads that had a magnitude of about one-quarter of the earthquake design loads. The transverse mode shapes and natural frequencies obtained from these tests were used in conjunction with the system identification procedure outlined.
