Model updating method for hybrid simulation based on global sensitivity analysis

Abstract: The hybrid simulation (HS) is a cost-effective and promising method for investigating the seismic performance of structures. This paper proposes a model updating method for HS to improve incomplete boundary conditions and model error, and develops criteria to select the updated parameters. First, an actual HS model updating is conducted to verify the effectiveness of uniform design as a parameter estimation method. This experiment shows that parameter sensitivity has a significant relationship with the update … Show more

“…Sudret [ 47 ] analytically derived the PCE-based global sensitivity indices formulae, and Cheng et al [ 48 ] and Wu et al [ 49 ] analytically derived global sensitivity indices formulae using SVR and RBF, respectively. In recent years, the application of global sensitivity analysis in the field of finite element model updating and damage identification for civil engineering structures has received much attention [ 50 , 51 , 52 ]. Surprisingly, global sensitivity analysis techniques to assess the long-term deflection affecting RC beams have not been developed or studied.…”

“…Hybrid simulation treats critical and/or complex components that are difficult to numerically model as experimental substructures, while the rest of the system is often easy to model and analyze as numerical substructures 20,21 . Due to the advantages of hybrid simulation, many studies have focused on numerical substructure and experimental substructure boundary correction, 22 compensation techniques for reducing actuator delay, 23 identification and modification of structural parameters for hybrid simulation model update methods, 24–27 Internet‐integrated geo‐distributed real‐time hybrid simulation platform, 28 force and displacement hybrid control strategies for solving multifreedom strong coupling problems 29 . These have made the hybrid simulation technique widely used in engineering 30,31 to be applied to the assessment of seismic performance of more complex and large engineering structures 32 …”
