Abstract/Summary Passive energy dissipation technique is widely used in structures to absorb earthquake energy as they are simple, easy to install and economical and, importantly, they do not rely on external power to operate. Metal yielding devices are widely used due to their simplicity in both design and implementation and they generally exhibit stable hysteretic behaviour. Yielding shear panel device (YSPD) is a newly proposed energy dissipating deivce that exploits the in-plane shear deformation of a steel plate to absorb energy. Recent research on YSPD demonstrated the development of FE models using ANSYS to obtain reliable force displacement reposne when subjected to cyclic loading. The current paper proposes a hysteretic mathematical model for YSPD, which is required to evaluate the performance of structures equipped with this device. Current research exploits the modified Bouc-Wen model, commonly referred to as Bouc-Wen-Baber-Noori (BWBN) model, to include the inevitable effects of pinching, strength degradation and stiffness degradation. Explicit mathematical formulations, devised using a total of 130 FE models, are proposed herin to appropriately predict the BWBN model paramaters for YSPD. Obtained relationships allow modelling for the hysteretic load-deformation response of YSPDs using the knowledge of easily available geometric and material properties. Cyclic response for a number of YSPDs, generated using the proposed formulation, are compared against those obtained from FE simulation and test results. Overall, good agreement is observed between the analytical predictions and test/FE results.
