Abstract
Nonlinear dynamic numerical modelling and analysis of concrete panels
subjected to blast loads is presented in this paper. Reinforced concrete panels of
dimension 1.0 1.0 m and different thicknesses and supported on four sides are
subjected to blast loads produced by the detonation of high explosive charges.
The modelling and analysis was conducted using ANSYS AUTODYN solver.
The accuracy of the model is verified against experimental results of blast load
tests on reinforced concrete horizontal slabs subjected to the detonation of high
explosive charges above them. The model was capable of simulating the
observed damage and displacement with reasonable accuracy. The verified
model is used for extensive parametric study to examine the effect of different
design parameters on the performance of reinforced concrete slabs under blast
loads. The design parameters considered in this study include the effect of
concrete compressive strength, panel thickness, reinforcement steel ratio,
arrangement of reinforcement steel, and boundary condition on the behaviour of
RC panel under blast load. The performance was evaluated in terms of maximum
displacement, extent of damage and energy absorbed.
Keywords: blast load, nonlinear numerical modelling, dynamic, ANSYS.
