In the past two decades, various self-centering bracing systems have been developed to enhance structural seismic resilience. However, compared conventional systems, their high initial cost and lower efficiency in controlling peak floor accelerations reduced economic benefits limited application engineering projects. Accordingly, viscous energy-dissipative brace (SCVDB) hybrid system (HB), synergistic combination of SCVDB buckling-restrained (BRB), emerged as innovative approaches with exceptional capabilities passive control over acceleration demand. Despite promise, a comprehensive understanding life-cycle structures equipped these remains limited. This study aims comprehensively highlight associated braced frames (SCVDFs) (HBFs) traditional (BRBFs) across heights using improved HAZUS assessment methodology. Focusing on 4-, 8-, 12-story buildings designed BRBFs, SCVDFs, HBFs, each maintaining identical inter-story drift ratios, research conducts dynamic analyses combined Monte Carlo simulations. Critical parameters such residual (RID) limits defined for demolition, construction costs SCVDBs, discount rates are considered. The reveal that expected annual earthquake-induced loss (EAL) mid- high-rise is more sensitive RID than those low-rise structures. SCVDFs HBFs exhibit EAL even without considering demolition situation. limit, significantly influence relative BRBFs. most scenarios, demonstrate superior SCVDFs. HBF effectively utilizes effects SCVDBs BRBs, substantially lowering achieving favorable within considered parameter range.

This study introduces a new type of shear panel damper that utilizes iron-based shape memory alloy (Fe-SMA) with enhanced low-cycle fatigue (LCF) resistance for structural damage control, particular focus on the effect solution treatment properties interest Fe-SMA. Material-level investigation was conducted first, aimed at establishing clear connection between microscopic structure and macroscopic properties, to determine most suitable method Fe-SMAs damping purposes. followed by laboratory tests Fe-SMA based receiving an appropriate treatment, along conventional metal dampers made low yield point steel LYP225 mild Q235. Results reveal among considered treatments, 1,100°C 1 h leads desired mechanical such as lower stress, increased ductility, longer LCF life, seismic applications. The demonstrates significant improvement in life total energy dissipation capacity compared traditional dampers. Finally, detailed numerical investigations were carried out analyze response. A calibrated micromechanics-based model, i.e., cyclic void growth employed predict fracture initiation under loading. approach achieved reasonable accuracy, assisting understanding distinctive behavior
