Abstract :
Iran is among the most earthquake-prone regions in the world, frequently experiencing severe seismic events that have resulted in significant human and financial losses. Research in earthquake engineering has consistently sought to mitigate such irreversible damages. This study examines the effectiveness of structural fuses in improving the rapid reoccupancy of steel structures. Four structural models—5, 8, 14, and 16 stories—were developed and subjected to nonlinear time-history analyses. Eleven earthquake records were employed in the analyses, including six near-fault and five far-fault ground motions. Following the evaluation of the influence of fuses on seismic response reduction, the Performance Assessment Calculation Tool (PACT) was used for qualitative damage assessment, focusing on the repair time needed to restore the structures to an operational state.
