In seismic response analysis of buildings against strong earthquakes, it is very important to appropriately set the model parameters of the building. Numerous methods have been proposed to identify these parameters. However, most are based on only linear analysis; some studies using nonlinear analysis noted difficulty in practical applications. In the present study, the Modal Iterative Error Correction method (MIEC method) is proposed to identify the nonlinear seismic parameters of buildings. The accuracy of this technique for RC structure is evaluated on the basis of shaking table test results.
