“…This can eventually lead to high-performance structural systems, particularly when combined with other advanced engineering materials (e.g., LYP steel). Jia et al (2018) performed a time-history analysis to investigate the seismic response of resilient steel frames with self-centering dual-core (Q690 and Q100 steel) buckling restrained braces (SC-DBRB) under moderate and severe earthquakes. Results exhibited less residual drift in the SC-DBRB frames than the BRBFs with normal strength steel core.…”

The all-steel self-centering multistage buckling restrained brace (SC-MBRB) with restrained cores consisting of different steel grades is an innovative hybrid system introduced to elevate the performance of conventional BRBs. This study submits a new configuration of SC-MBRB with cores made of high-strength (HSS), ultra-high-strength (UHSS), and low yield point (LYP) steels. A trilinear hysteretic model is proposed to simulate the cyclic behavior of SC-MBRBs. The seismic performance of SC-MBRB, including cyclic response, energy dissipation, re-centering property, and plastic deformations, was investigated by finite element (FE) analysis. Considering the specification of HSS and UHSS, including fracture behavior, low cycle fatigue, and ductility, the effect of different ratios of strength and cross-sections was investigated. Eventually, models with varying core lengths whose specifications were determined based on the Coffin-Manson relationship were examined. The results indicate that the introduced SC-MBRB has provided suitable seismic performance. Moreover, the trilinear kinematic hysteretic model could successfully predict the hysteretic behavior of SC-MBRB. Furthermore, applying maximum HSS core length with minimum LYP core length and combining S960 with the LYP100 provides the most reliable results.

Summary An innovative self‐centering steel–timber hybrid shear wall (SC‐STHSW) system is proposed as a promising structural solution for earthquake‐resilient buildings. The SC‐STHSW is composed of posttensioned (PT) steel rocking frame and infill light‐frame wood shear wall. The PT steel frame provides self‐centering capability, whereas the infill wood shear wall improves the lateral stiffness and the load resistance. Meanwhile, friction dampers are assembled into the connections between the steel frame and the infill wall to provide energy dissipation. Theoretical analysis and cyclic loading test were conducted to comprehend the load‐resisting behavior of the proposed SC‐STHSW system, and closed‐form solutions of the moment, shear, and axial force distribution along the length of the steel beam were formulated. Moreover, a nonlinear finite element model was developed, and the model was further used to verify the derived theoretical formulas. Results showed that the SC‐STHSW system was able to undergo large interstory drift without the development of plastic zones in the steel frame members, which resulted in very small residual deformation. The presented experimental and numerical results aim to provide a practical structural solution for high‐performance earthquake‐resilient buildings.

“…Mottier et al [36], use rocking systems in the retrofitting of existing steel structures. Jia et al [37] suggested rocking dual-steel has trilinear hysteretic behavior and lead to mitigation of residual drift as a result of early re-yielding of low-yield point steel. The results of Moradi and Burton [38] showed that the seismic response of the controlled rocking steel braced frames do not affect considerably by changing design parameters such as post-tensioned bars modulus of elasticity and strain hardening ratio of the fuses.…”

Concentrically braced frames (CBFs) as one of well-known stiff and common lateral force resisting systems often show limited ductility capacity under severe earthquakes. This study proposes rocking zipper braced frame (RZBF) to improve the drift capacity of CBFs which is based on combination of rocking behavior and zipper columns. In the RZBF system, rocking behavior permit the braced frame to uplift during the earthquake and then restoring force induced through post-tensioned bars self-center the frame to its initial state.Also, zipper columns can decrease the concentration of damage by distributing the unbalance force at the mid bay over the frame's height. To assess the performance of RZBF, a comparison study is carried out considering CBF, rocking concentrically braced frame, zipper braced frame and RZBF. For this purpose, some frames structures are designed and nonlinear time history analysis conduct under a set of earthquake records. Seismic responses such as roof drift ratio, gap opening at the column-base interface, forces of top story braces and post-tensioned bars are taken into consideration. The results show that the proposed RZBF has better performance among the others and zipper columns can improve the behavior of rocking systems.
