The increase in the number of explosions affecting critical infrastructure, whether civilian or military, both in conflict zones and beyond, has led to the development of numerous studies aimed at analyzing the behavior of different types of structures. This work presents both experimental results and numerical simulations carried out using numerical methods within several research projects. The study primarily focuses on the behavior of reinforced concrete beams, slabs, and complete structures , as well as masonry walls and reinforced concrete block walls . The walls are analyzed using various protection systems designed to prevent the generation of secondary fragments. The Finite Element Method (FEM) is employed as the primary numerical approach, combined with Smoothed Particle Hydrodynamics (SPH) for both explosive modeling and the simulation of surface fragment formation.
