Influential Article Review — The Effect of Seismic Excitation on the Passive Stiffness of a Seismically Isolated Bridge Deck

Abstract

This paper examines the performance of modified bridge elements under simulated earthquake excitations. We present insights from a highly influential paper. Here are the highlights from this paper: This study is on the seismic performance assessment of a seismically isolated bridge structure with passive stiffness modification implementation. Performance of the passive stiffness modification approach is compared with semi-active control implementation on the bridge deck. El Centro NS (north-south) and Kobe EW(east-west) earthquake excitations are used for the dynamic simulations of the passive case. Results are given in a comparative way for the uncontrolled bridge deck, passive stiffness modification implemented and semi-actively controlled, seismically isolated bridge deck (Yanik & Aldemir, 2018). Frequency dependent acceleration, velocity and displacement response transmissibility ratios are defined to examine the results. For our overseas readers, we then present the insights from this paper in Spanish, French and German.
