Seismic Control of Benchmark Highway Bridge Using Fiber-Reinforced Elastomeric Isolator
In this study, the seismic response of a benchmark highway bridge is scrutinized with a passive control system named Fiber-Reinforced Elastomeric Isolator (FREI). Bearing with fiber reinforcement and elastomeric damping material is called fiber-reinforced elastomeric isolator bearing. Advancement of fiber materials is striking nowadays whose stiffnesses are practically identical to steel. So as per efficient and innovative point of view, this isolator is supposed for seismic analysis. The Phase I problem of the benchmark highway bridge is considered for this study. The ground acceleration is applied at all supports of the bridge. A comparative study on the basis of displacement amplitudes has been encountered under six real ground motions. Evaluation criteria are also established under different boundary conditions which highlight that substantial reduction of seismic response can be achieved by using higher displacement amplitude values of FREI. It is observed that peak responses of base shear and displacement at mid-span are effectively reduced by employing certain range of displacement amplitude values.
