Most of modern seismic design codes adopt the performance-based approach by defining a pre-defined level of safety for different limit states.

Abstract
Most of modern seismic design codes adopt the performance-based approach by defining a pre-defined level of safety for different limit states. These safety margins are im-plicitly defined into the definition of detailing provisions as well as in partial safety factors for both actions and materials strength. Moreover, such implicit provisions are related to the specific structural typology; hence, the structural safety can change for different typologies designed for the same site. This study investigates the seismic performance of typical Italian RC precast buildings by means of an extensive parametric study. Both the structural typology and the geometrical configurations are defined in order to represent the most common prac-tice in the country. The investigated buildings are located in five sites with different levels of seismic hazard and two soil types are also considered. The collapse assessment is investigat-ed by means of multi-stripe analyses, performed by non-linear dynamic analyses at 10 intensi-ty levels.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
