System identification in structural engineering

A review of representative research reported in journal articles in the field of structural systemidentification published in journals since 1995 is presented. the paper is divided into five sections basedon the general approach used: conventional model-based, biologically-inspired, signal processing-based,chaos theory, and multi-paradigm approaches. most of the published papers deal with small and academicproblems. system identification of large real-life structures with nonlinear behavior subjected to unknowndynamic loading such as strong ground motions is challenging. it is believed a multi-paradigm approachis the most effective strategy for system identification of large structures subjected to dynamic loading.
