Abstract: “The collapse probability of structures is determined through two approaches of probability of exceedance in terms of EDP-Based and IM-Based approaches. Pertaining to characteristics of structure and types of excitations, these two values may evaluate the probability of collapse in lower and upper estimation. In this study, through combining these two estimations, a precise measure of collapse probability is exhibited. To evaluate collapse capacity of structures and implementation of probabilistic scheme in structure performance assessment, incremental dynamic analysis (IDA) and fragility curves are used. The systematic view of two approaches of collapse probability consists of engineering demand (EDP-Based) and intensity measure (IM-Based) are considered in series forms. The study results show that the combination of these two aforementioned schemes exhibit comprehensive vision of collapse probability of structures which are very important in performance evaluation of structures.”
