Parameter identification for nonlinear structural model using modal iterative error correction method

Abstract

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 application. In the present study, the Modal Iterative Error Correction (MIEC) method is proposed to identify the nonlinear seismic parameters of buildings. The accuracy of this technique is evaluated based on shaking table test results.
