Parameter Identification for Hysteretic Models of Torsional-Shear Buildings

摘要

In this study, we present an algorithm for estimating the parameters of a hysteretic model of a single-story torsional-shear building. We adopt the Bouc-Wen model to parameterize the nonlinear force-displacement loops of the structure. Using an Extended Kalman filtering approach, and data gathered during a damaging event, we aim to localize hysteresis at the level of individual elements that comprise the lateral load-resisting system.
