Large-Scale Shake Table Test Verification of Bridge

Large-Scale Shake Table Test VerificationofBridge Condition AssessmentMethods Methods that identify structural component stiffness degradation by pre- and postevent low amplitude vibration measurements, based on a linear time-invariant (LTI) system model, are conceptually justified by examining the hysteresis loops the structural components experience in such vibrations.

Shaking Table Tests of Curved Bridge considering Bearing

On the basis of theoretical research, the scholars have also carried out someshaking table testson isolatedbridges[18–24]. Most of these isolatedbridge testsare carried out for the straightbridge, and theshaking table testsfor isolated curvedbridgesare rarely studied.

Shaking TableModelTest for Vertical Seismic Responseof

Based on theshaking tablemodeltestof abent-type aqueduct on the rigidity foundation, the dynamic characteristics and seismic performance of the aqueduct structure subjected to vertical seismic waves are discussed. Thetestindicates that (1) Water in the aqueduct makes the mass of the structure larger and the frequency of the model structure lower.

The modifications to this procedure necessary to align with the objectives of the new system are straightforward and could be implemented within current design practice. A modeling strategy for the pre-tensionedbentsystem is also proposed and specific aspects of this approach are validated against the subassembly andshaking table testresults.
