Abstract (EN): The purpose of the presented work is the behavior assessment of reinforced concrete frame structures with irregularities in elevation. Three six-storey frame structures with different degrees of irregularity in elevation were selected and their responses were compared with the ones of a corresponding regular structure. In this study, the effects of the variation of the axial force in the columns and of different contributions of slab width to the beams’ flexural strength were investigated. In addition, a structure similar in configuration with one of the previously selected was defined and designed using current Portuguese codes to perform a comparison between different design approaches. Structural performance was assessed by comparing local ductility levels, displacements, inter-storey drifts and damage indices of the irregular frames and the regular one.
