Numerical Study of Damage Model for Reinforced Concrete Beam under Complex Boundary Condition Subjected to Air Blast Load

Abstract:

Explicit FEM model ANSYS-DYNA is applied to simulate dynamic response and damage morphology of RC beam under blast loading. The dynamic response and damage morphology of reinforced concrete beam is analyzed under the different burst points, different explosive locations with the same proportion distance. The results show that: Under the same blast loading, the extent of damage of RC beam under complex boundary was lighter than the simply supported beam because of the stiffness contribution of slab and column. Acceleration at the half span point of the beam was 1/3 of simply supported beam, and the explosion shock attenuation was obvious.
