Review on Web Buckling and Hysteretic Behavior of Shear Panel Dampers

Abstract

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.

Study on Seismic Behavior of Trapezoidal Corrugated Steel Plate Shear Wall Structure With Pec Column

“…In the above research, H-section steel columns were mostly used as the SPSWs's vertical edge members. However, under the additional influence of the steel plate tension field, the H-section steel columns were prone to premature local buckling, making the frame columns flexural and torsional unstable, and the effective anchorage of thin steel plate walls was lost, which was not conducive to the performance of SPSWs after buckling [13][14][15]. The partially encased composite (PEC) columns had a high bearing capacity, good ductility, fire resistance, seismic resistance, and convenient and economical manufacturing [16][17][18][19][20].…”
