Physical parameters identification for full?scale ten?story reinforced concrete building with degrading tri?linear model by modal iterative error correction method

To assess the post-earthquake seismic safety of buildings, it is crucial to predict response, and necessary set appropriate physical parameters response analysis model. Numerous methods have been proposed identify parameters. However, most them are limited linear systems, previous researches on nonlinear systems difficulties in practical applications. In this paper, a model identified for full-scale ten-story reinforced concrete building with degrading tri-linear stiffness by modal iterative error correction (MIEC) method, accuracy technique discussed comparing shaking table test.
