Abstract (EN): This study presents the development of a set of fragility functions for six reinforced concrete building typologies, categorized based on the date of construction (which has a direct relation with the design code level) and number of storeys (height of the building). The structural fragility of the Portuguese building stock has been the target of only limited investigation in recent years and, moreover, the existing studies relied mainly on simplified methodologies which might not be sufficient to represent the structural characteristics of the RC building typologies in Portugal. An analytical methodology was adopted in which thousands of nonlinear dynamic analyses were performed on 2D moment resisting frames with masonry infills, using one hundred ground motion records as much as possible compatible with the Portuguese tectonic environment. The generation of the structural models was carried out using the probabilistic distribution of a set of geometric and material properties, compiled based on information gathered from a large sample of drawings and technical specifications of typical Portuguese reinforced concrete buildings, located in various regions in the country. Various key aspects in the development of the fragility model are investigated herein, such as the selection of the ground motion records, the definition of the damage criterion and the evaluation of dynamic (i.e. period of vibration) parameters of the frames. The resulting fragility model can be applied directly in earthquake loss assessment, which is a fundamental tool for the development of risk mitigation actions. © 2014 American Society of Civil Engineers.
