Abstract

This study investigates the influence of concrete jacketing on the performance of steel columns subjected to blast loading, which can lead to progressive collapse. Using Finite Element Method (FEM) simulations, the research evaluates concrete-encased steel columns with different concrete cover thicknesses to measure their resistance to lateral displacements induced by blasts. Findings reveal that increasing the thickness of the concrete cover markedly improves the column's ability to withstand such loads. The study also highlights that steel has better energy dissipation properties than concrete. It examines how the combined challenges of progressive collapse and blast loading influence the overall structural response of a building, identifying potential failure points in structural members. This research emphasizes the need to integrate considerations of both blast resistance and progressive collapse potential into structural design, aiming to enhance the performance and resilience of steel columns and contribute to the development of more robust structural systems capable of surviving extreme events and reducing the risk of catastrophic failure.
