Abstract:

Based on the finite element analysis software of ANSYS /LS-DYNA，a finite element model of reinforced concrete structure is established，and the dynamic response of this structure is analyzed. The results shows that the reinforced concrete structure has a good anti-explosion performance. The simulation results provide references for the anti-explosion design，anti-explosion reinforcement and structure form selection.
