Nonlinear seismic performance study of D‐type self‐centering eccentric braced frames with sliding rocking link beams

Abstract: This paper presents a nonlinear numerical simulation study of the D-type self-centering eccentric braced frame system with a sliding rocking link beam (SCEBF-SRL) to overcome the beam-growth problem. The re-centering capability of such SCEBF-SRLs is enabled by post-tensioned (PT) steel-stranded cables. Replaceable hysteretic dampers termed RHD are used as seismic fuse devices for energy dissipation, while the friction force due to the relative movement of the sliding rocking link beam inside the column corbels… Show more

“…The lateral movement of the two columns is restrained by the side load-transfer beam, which would also carry the major part of the gravity loads. 17 The energy dissipation capacity of the system is mainly provided by replaceable hysteretic damper (RHD) devices consisting of multiple metallic hysteretic trapezoidal plates and a holder bracket. Each plate is divided into a tapered length and a rectangular tongue which is directly inserted into the slots of the holder bracket.…”

“…Keivan and Zhang 16 studied the nonlinear seismic performance of Y‐type self‐centering eccentrically braced frames (SCEBF‐Y) structure with vertical links. Rezvan and Zhang 17 proposed the D‐type SCEBF with a sliding rocking link beam to overcome the beam growth. They included the effect of friction force due to the sliding movement of the rocking link in the analytical formulation and numerical simulation.…”

“…A promising solution, which is known as self-centering framed structural system, has received extensive research interests [ 6 , 7 ]. Additional self-centering members/devices, such as beam-to-column connections [ 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 ], braces [ 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 ], and dampers [ 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 ], with the capability of returning to their initial resting position after earthquake, are proven to be effective in eliminating the residual story drifts when they are installed in the corresponding frame systems. Ricles et al [ 42 , 43 ] developed a post-tensioned (PT) moment-resisting connection where seat angles were utilized as an energy-dissipation source.…”

“…Joint closing usually is guaranteed either by the structure's self-weight (rocking frames) 10,11 or a post-tensioned system (post-tensioned selfcentring frames) . [12][13][14][15][16][17] The post-tensioned self-centring (PTSC) frames utilise post-tensioned cables to provide recovery forces to close joints. The pioneering work of PTSC frames was the PREcast Seismic Structural Systems (PRESSS) program carried out in the 1990s.…”

“…20 There are two types of damping devices for application within PTSC frames. They are sacrificial hysteretic devices 17,21 and frictional damping devices. [22][23][24] These devices exhibit a parallelogram-shaped hysteretic curve.…”
