Abstract Friction pendulum bearings (FPBs) have been widely adopted in bridge engineering, yet pier reinforcement design for large FPB-isolated bridges still suffers from correlation neglect and high computational cost. This study addresses substructure reinforcement design of multi-span continuous girder bridges equipped with FPBs under non-stationary seismic actions.
Abstract Traditional isolation design for continuous girder bridges often focuses on single-parameter tuning, overlooking the complex interactions among yield strength, pre-yield stiffness, and post-yield stiffness. This paper proposes a multi-parameter optimization method to systematically investigate the nonlinear influence of each parameter on the seismic performance of bridges.
