Progressive Collapse of RC Frame Structures with Effect of Soil Structure Interaction Using Software -A Review

The phenomenon of progressive collapse in structural engineering refers to a failure mechanism where a localized failure precipitates a chain reaction, ultimately leading to the total collapse of a building. Literature emphasizes the criticality of understanding load redistribution mechanisms and structural robustness, particularly in multi-storey reinforced concrete (RC) buildings. A review is presented here to understand the need of considering various factors responsible for failure of building due to accidental loads. Study signifies that the removal of exterior corner columns poses significant risks due to increased axial forces, bending moment and base shear underscoring the need for robust design strategies. The study also suggests of considering soil structure interaction, to understand its role in progressive failure.
