- Abstract
The behavior of isolated integral bridges at the pier (IBP) is scantly reported in the literature. Herein, its behavior is studied in distinction with the isolated conventional bridge under multi-component far and near-field earthquakes. Nonlinear time-history analysis of isolated and corresponding fixed-base bridges having the same geometry is conducted. The response reduction of isolated bridges compared to fixed-base bridges is used as an index to characterize the relative performance of the isolated IBP. The study shows isolating IBP provides greater response reduction and greater protection against damage measured in terms of the maximum plastic hinge rotations that occur in the bridges.
