A method is proposed for designing RC structures that satisfy prescribed requirements in terms of frequency of exceedance of a number of performance levels. The method assumes the period and base shear ratio as the two most relevant (global) design variables. It makes use of pushover analysis to evaluate an approximate median IDA curve employed for evaluation of the mean annual frequency of exceedance of the performance levels, according to the closed-form expression by Cornell and co-workers (Cornell et al. 2002). Two examples illustrate the application of the method, its current limitations and perspectives.

Abstract
A method is proposed for designing RC structures that satisfy prescribed requirements in terms of frequency of exceedance of a number of performance levels. The method assumes the period and base shear ratio as the two most relevant (global) design variables. It makes use of pushover analysis to evaluate an approximate median IDA curve employed for evaluation of the mean annual frequency of exceedance of the performance levels, according to the closed-form expression by Cornell and co-workers (Cornell et al. 2002). Two examples illustrate the application of the method, its current limitations and perspectives.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
