[2035] RESPONSE PREDICTION AND DAMAGE EVALUATION OF A REINFORCED CONCRETE STRUCTURE BASED ON LIMITED SENSOR DATA AND THE KALMAN METHOD
Keywords:Reinforced concrete、Response prediction、Damage evaluation、Kalman method
The response and damage level of a reinforced concrete structure is evaluated using a simulated performance curve updated by the Kalman method to match the observed response of a 1/4-scale four-story reinforced concrete frame with shear walls subjected to a series of earthquake simulation tests. The capacity spectrum method is used to estimate structural response with the damping model updated by Kalman method. Damage levels are defined using characteristic points. Estimated drift error is within 35% of measured drift, and the predicted damage level matches well with the observed damage level.
