Seismic Fragility Assessment of Masonry Infilled Reinforced Concrete Frames

Seismic fragility assessment of masonry infilled reinforced‒concrete frames was analysed. Three model structures with different infill configurations, were used. Developed and interpreted were the probabilistic fragility curves using Incremental Dynamic Analysis (IDA) and a set of seven earthquake records was used. Influence and contribution of infill walls to the system behaviour was evaluated. Results are presented as median values of the fragility curve for four limit states corresponding to the damage scale and damage measure of interest (Inter‒storey Drift Ratio, IDR). It could be concluded that fully‒infilled frame had 50% lower values of maximum Inter‒storey Drifts and had probability to survive up to 3 times higher intensities of spectral acceleration in regard to the bare frame.
