The influence of the seismic performance of existing bridges on the functionality of communication infrastructures is widely recognized as a crucial issue. Therefore, Hybrid Simulation with Dynamic Substructuring (HS-DS) was selected for assessing the seismic response of a two-pier reinforced concrete (RC) bridge at the Eucentre TREES Laboratory of Pavia (Italy). In order to simulate a consistent degradation between the physical and the numerical pier, the use of the Unscented Kalman Filter as parameter identification tool was explored. A novel parallel partitioned time integrator tailored to first order systems allowed for the straightforward accommodation of the filter. © International Conference on Advances in Experimental Structural Engineering.
