ABSTRACT:

Recently shear panel dampers (SPDs) have been applied to building and bridge structures widely, showing good effects in seismic hazard mitigation as passive energy dissipators. The mechanism of SPDs for dissipating earthquake-induced energy is through inelastic shear deformation of the metal. This paper firstly gives a brief introduction to the new development of configuration and material of SPDs. Then two important issues, namely, web buckling and hysteretic behavior of SPDs are mainly addressed. Several structural parameters, which have influences on bearing capacity, ductility and energy dissipation capacity of SPDs, are also discussed, with regarding to web slenderness ratio, stiffness of stiffeners, and contribution of flanges. Additionally, various restoring models of

SPDs, which is developed to be used in evaluation of seismic control structures, are also discussed together with their hysteretic behavior. Finally, application of SPDs in building and bridge structures is presented, pointing out the issues deserving further study and potential application to new field of civil engineering.
