bridge bent shaking table validation tests

Twolarge-scale shake table experiments, one on a two-columnreinforced concrete(RC)bridge bent specimen, and the other on a two-spanthree-bent RC bridge specimenwere performed, in which specimens were subjected to earthquake ground motions …

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.

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.

The lack ofshaking table dataon full-scale benchmark specimens thatvalidateour understanding of the highly non-linear, multi-axial performance of full-scalebridge columnssubjected to input motions representative of large earthquakes, has led many researchers,bridgeengineers and practitioners to call for thevalidationof current experimentaltesting, design and analysis methods.

Theshaking table testof ascale cable‐stayedbridge modelwas conducted, and the vibration of the tower was recorded by a camera. The linear and nonlinear displacement responses of the tower under differentearthquake ground motionswere identified.

Full-Scale Seismic Performance Testing ofU.S. HighwayBridgeColumn. The current seismic design procedure forbridgecolumns in the U.S. are based on theoretical and computational models that are calibrated against experimental data. Nearly all of these data are fromtestson reduced-scale specimens.

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.

Shaking table testswere carried out to study the failure mode, dynamic characteristics, acceleration and displacement response, dynamic magnification factor, ductility, and energy dissipation of hollow rectangular piers. This paper focuses on the failure mode and response analysis ofshaking table tests…

The limited damage and residual drift aftertestswere considered as its main advantage. Cheng verified this significant advantage byshaking table tests. Nonlinear elastic response has no or little energy dissipation in hysteresis, which also limits the force demands.

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.
