Analytical Evaluation on Structural Performance and Optimum Section of CHS Damper
This study aims to evaluate the effective size, section
and structural characteristics of circular hollow steel (CHS) damper.
CHS damper is among steel dampers which are used widely for
seismic energy dissipation because they are easy to install, maintain
and are inexpensive. CHS damper dissipates seismic energy through
metallic deformation due to the geometrical elasticity of circular shape
and fatigue resistance around connection part. After calculating the
effective size, which is found to be height to diameter ratio of √3,
nonlinear FE analyses were carried out to evaluate the structural
characteristics and effective section (diameter-to-ratio).
