dc.description.abstractTwo new closed-form expressions representing the mean rate of exceedance of a given limit state arepresented herein. These proposals overcome limitations that were identified with the original formulationof the well-known SAC/FEMA approach. The new expressions involve new parametric functions for themodeling of the seismic hazard data and for the demand evolution for increasing values of the earthquakeintensity measure. Given the carefully selected parametric form of these functions, mathematical tractabilityis able to be maintained to establish two new closed-form solutions representing the mean rate of exceedanceof a given limit state. The function proposed for the hazard exhibits nonlinear behavior in log-log space andis able to represent the actual hazard data over a wider range of earthquake intensity levels. The functionproposed for the demand evolution addresses issues related to the inadequate performance of theSAC/FEMA approach when force-based demand parameters such as the shear force are considered. To illustratethe applicability of the new closed-form solutions, the probability of occurrence of several limit states isdetermined for a reinforced concrete structure
