FRAGILITY ASSESSMENT OF NON-DUCTILE RC FRAMES SUBJECTED TO POUNDING

Out-of-phase vibrations of series configured structural systems subjected to ground shaking scenarios lead to collisions between adjacent buildings. Such collisions, known as structural pounding, can lead to devastating failures. This study aims to analyze the effects of structural pounding on the displacement-based demands of a non-ductile reinforced concrete frame against a stiffer frame for floor-to-column interactions. The investigation uses the empirical cumulative distribution function to derive fragility curves for estimating pounding risks. It is inferred that such a fragility curve generation technique proves to be accurate and computationally economical for the analytical risk estimation of pounding.
