Pinching Effect in Yielding Shear Panel Passive Device

The paper describes a modeling technique of the hysteretic response of yielding shear panel device (YSPD). This device is used for seismic energy dissipation in frame structures. The generalized Bouc-Wen-Baber-Noori (BWBN) hysteretic model is adopted in this work. Simulink is used to develop the BWBN model of the YSPD. The model parameters are calibrated based on experimental results conducted on the YSPD. The developed hysteretic model of the YSPD is then incorporated in state-space approach to evaluate the response of dissipative structures. Assessment of effectiveness of the YSPD in alleviating structural response and the effect of pinching on the overall response of the structure is made.
