Abstract  A numerical model using the coupled smoothed particle hydrodynamics-finite element method (SPH-FEM) approach is presented for analysis of structures under blast loads. The analyses on two numerical cases, one for free field explosive and the other for structural response under blast loads, are performed to model the whole processes from the propagation of the pressure wave to the response of structures. Based on the simulation, it is concluded that this model can be used for reasonably accurate explosive analysis of structures. The resulting information would be valuable for protecting structures under blast loads.

Key words： Smoothed particle hydrodynamics (SPH)      Finite element method (FEM)      Reinforced concrete structure      Explosion
