Role of resilience in selection of R factors for an RC building

In the seismic design of a reinforced concrete building, selecting appropriate response reduction factor (R) is vital for building’s response. Indian Standard (IS) 1893-2016 provides R values 3 and 5 ordinary moment resisting frames special frames, respectively. As factors are used to incorporate non-linearity, selection should be based on performance in terms resilience. Since IS does not provide any clause background aspects, study emphasizes with respect functionality, level, this study, high-rise building was designed various (R = 3, 4, 5, 6). To estimate five different recovery paths (RP-1 RP-5), which match real scenario, were used. The each case observed at two levels, Design Basic Earthquake (DBE) level MCE level. Variations ductility demand, resilience observed. obtain lateral force DBE by reducing actual base shear placed structure. maximum yielded high demand loss result shows that considered can 6 since its almost 50%; hence, possible cost. lies CP-C Considering found 6. This helps stakeholder designer R, requirements
