Recent advances on the hybrid simulation of bridges base on partitioned time integration, dynamic identification and model updating

Abstract

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.
