Numerical modelling of reinforced concrete columns subject to coupled uplift and shear forces induced by internal explosions
This article investigates the effect of time-variant coupled uplift forces and lateral blast pressures on the vulnerability of reinforced concrete columns when subjected to internal explosions. Detailed examination of archived events has demonstrated that confined blast can induce significant uplift forces on concrete columns carrying predominantly compression loads. These uplift forces can deteriorate the strength of concrete columns leading to destabilisation and a critical loss of structural adequacy. This research employs the applied element method together with high-resolution computational fluid dynamics simulations to model column response due to complex vented and contained internal blast environments. Results from a number of parametric studies highlighted the important effect of uplift forces and blast wave confinement with regard to the overall vulnerability of the column to internal building detonations. This research will be of direct importance to both practitioners and researchers involved with protective design of buildings.
