Abstract:
Chapter 16 presents a numerical analysis methodology for assessing the structural response of reinforced concrete (RC) structures subjected to aircraft impacts and high-explosive (HE) detonations. The study employs advanced computational techniques to simulate the dynamic effects of high-velocity impacts and blast loads on RC structures, providing insights into failure mechanisms and structural integrity. The methodology integrates finite element modeling with specialized material models to capture the complex interactions between impact forces, material deformation, and failure propagation. Various impact scenarios, including missile strikes, HE detonations near RC slabs, and full-scale aircraft collisions, such as an F-4 Phantom and a Boeing 747 crashing into thick concrete walls, are analyzed. The results highlight the influence of material properties, reinforcement configurations, and structural geometry on impact resistance. Additionally, simulations of HE detonation in tunnel structures with inner steel liners provide critical data for designing blast-resistant infrastructure. The findings contribute to enhancing protective measures for critical structures and improving numerical modeling techniques for extreme loading conditions.
