Finite Element Simulation of Blast Loads on Reinforced Concrete Structures using LS-DYNA

摘要

The behavior of reinforced concrete structures under blast load is analyzed by LSDYNA. A new load generation method is proposed so that blast load can be applied to large civil engineering structures, such as highway bridges. The influence of time step and mesh size on simulation results is investigated. Three examples including flexural failed beam, brittle failed beam and undamaged column under blast load are presented. Numerical results match reasonably well with experimental data.
