Descrição: dc.descriptionQuantitative analyses of structural resistance are useful during the design process to prevent the occurrence of progressive collapse. Buildings subjected to continuous instances of expected/non-expected loadings due to extreme events (e.g., earthquakes, explosions, floods, hurricanes) can collapse. A lack of specific knowledge from the designer and poor maintenance can affect collapse analyses. In this paper, the probability of failure for pancake collapse with respect to bending collapse for reinforced concrete (RC) multi-storey buildings is estimated. New combinations regarding the elastic/plastic behaviour of the material under distributed loadings on beams are proposed. Numerical 2D finite element method (FEM) analyses are carried out to model these buildings. Also, simplified dynamic analyses are carried out. The outputs are plotted in terms of the probability of failure for pancake collapse as a function of column compressive strength and the number of removed columns. The results show that the presence of elastic beams can influence the pancake collapse of columns, and, for buildings composed of several elements, the elimination of few elements has little impact on their stability.-
