Cost assessment of an isolated bridge with soil-structure interaction
Abstract eng: Bridges are lifeline structures acting as an important link in surface transportation network and their collapse under seismic excitations affects social and civil functionality. Historical bridge seismic collapses have proved the significant role of structure interaction (SSI). The paper aims at evaluating bridge protection and seismic strengthening applying isolation technique. It is based on the application of a Performance-Based Earthquake Engineering (PBEE) methodology, introduced by the Pacific Earthquake Engineering Research (PEER) center. The study presents a representative two—span bridge with several isolated configurations as affected by soil compliance. Isolation technique contribution is assessed in terms of cost quantities with Peak Ground Acceleration levels. The study can be considered a first attempt to evaluate seismic effects of SSI by taking into account economic performance.
