Accounting for Resilience in the Selection of R Factors for a RC Unsymmetrical Building

Several design codes consider the non-linear response of a building by using one most important seismic parameters, called reduction factor (R). The lack detailed description R selection creates need for deeper study. This paper emphasises methodology proper based on resilience aspects. Unsymmetrical/irregular buildings have become common in recent times due to aesthetic purposes. However, because complexity torsional effect, is even more difficult this type building. Therefore, high-rise G+10-storey L-shaped herein considered. has re-entrant corners structural/plan arrangement. Different factors were used design, considering subjected both unidirectional and bidirectional loading scenarios. with respect various (R equal 3, 4, 5 6) terms its performance level, functionality, damage ratio was assessed at two levels, i.e., basic earthquake (DBE) maximum considered (MCE). study concludes that, above criteria along aspect, up 4 can be recommended loading, whereas 3.
