Abstract

A multi-constitutive model simultaneous-updating-based online numerical simulation method is proposed to deal with the incomplete boundary condition problem and modeling errors in hybrid simulation. The structural responses are calculated using the overall structural model, whose constitutive model parameters are updated online utilizing the experimental data via the unscented Kalman filter. The effectiveness and feasibility were validated using a plane reinforced concrete frame and a spatial reinforced concrete frame equipped with buckling-restrained braces. Results indicated that estimating multi-constitutive model parameters simultaneously with measured restoring force can significantly enhance the model reliability, and the overall accuracy of the hybrid simulation was improved.
