Özet
A new hysteretic damper is developed for deployment in Chevron-braced frames of buildings to improve their seismic performance. The new damper, Torsional Hysteretic Damper for Frames (THDF), is a mechanical device designed to utilize torsional yielding of cylinders made of ductile steel to dissipate the imposed energy through seismic movements. The damper is distinguished by a variable, displacement-dependent post-elastic stiffness. This feature of the damper is intended to improve the height-wise distribution of story drifts and reduce the drift concentration in multistory buildings. Following the conceptual development of the damper, derivation of forcedisplacement equations and other analytical studies necessary to implement the damper in practice are performed. In this paper, the new damper is introduced and a summary of performed analytical studies are presented.
