Experimental Study of Cylindrical Steel Slit Damper for Passive Energy Dissipation
This paper presents a novel cylindrical steel slit damper, named the CSSD, designed for passive energy dissipation. The CSSD consists of a steel cylinder with multiple axial slit cuts to form strips, which dissipates energy by flexural yielding under the torsional deformation of the cylinder. In this study, we derived formulas to evaluate the initial torsional stiffness and torsional yield strength of the device. We then conducted cyclic loading tests on three specimens to verify the device's performance, and found that all specimens exhibited stable hysteretic behavior. The relationships between torque moment and torsional angle for the three specimens were discussed. The torsional stiffness and yield strength showed good consistency with the theoretical prediction. Results of this study indicate that the stiffness and strength of the CSSD can be easily modified or scaled up to meet actual structural requirements.
