Challenges in Modelling Reinforced Concrete Panels Subjected to Blast Load - A Critical Review

Abstract

Reinforced concrete panels are widely used in modern facilities, and evaluating their blast loading capacity is vital for security-critical assets. Due to the high impulsive nature of blast loads, the response of reinforced concrete panels is characteristically different from that under static or low dynamic load conditions. The failure of individual components often initiates the blast load's destructive effects on the entire structure. The material breach can be caused by stress wave localized effects before the general structural response becomes significant. Numerical methods are one of the key methods for studying the behaviour of reinforced concrete panels under blast load. This paper aims to review the current state of practice in modelling reinforced concrete panels and predicting their blast capacity and failure mechanisms under blast load. The work addresses the research gaps associated with using advanced finite element modelling as compared to test results.

Difficulties encountered in modeling blast-loaded reinforced concrete panels

“…As such, the analysis and modeling of blast-loaded reinforced concrete panels stand as a pivotal area in the realm of structural engineering, demanding meticulous attention to detail and precision. The European region, characterized by diverse construction practices, stringent regulations, and varying blast load scenarios, presents a unique landscape for studying and addressing the challenges associated with modeling blast-loaded reinforced concrete panels (Mohammed, 2022) [1] . The ramifications of blast-induced forces on structural elements, especially reinforced concrete panels, are multifaceted and multifarious.…”
