Residual axial capacity of reinforced concrete columns subject to internal building detonations
Residual axial capacity of reinforced concrete columns subject to internal building detonations
This paper details the development of an engineering assessment procedure for reinforced concrete column failure when subject to coupled uplift and shear forces typically induced by vented internal building detonations. This is based on a set of comprehensive parametric studies conducted using advanced Computational Fluid Dynamics and transient structural dynamic modelling techniques. These analyses are ratified and underwritten by independent verification using archive experimental data and alternative advanced numerical simulations. Results from the parametric studies are analysed using a nonlinear curve fitting technique to develop a set of assessment charts quantifying the extent of overall damage and residual axial column capacity when subject to internal building detonations. Application of the assessment procedure is demonstrated and the effect of compressive strength of concrete, column orientation and slenderness on damage behaviour and residual axial capacity are discussed. The developed assessment method will be of direct relevance to both practitioners and engineers involved with the protective design of buildings.

Abstract
This paper details the development of an engineering assessment procedure for reinforced concrete column failure when subject to coupled uplift and shear forces typically induced by vented internal building detonations. This is based on a set of comprehensive parametric studies conducted using advanced Computational Fluid Dynamics and transient structural dynamic modelling techniques. These analyses are ratified and underwritten by independent verification using archive experimental data and alternative advanced numerical simulations. Results from the parametric studies are analysed using a nonlinear curve fitting technique to develop a set of assessment charts quantifying the extent of overall damage and residual axial column capacity when subject to internal building detonations. Application of the assessment procedure is demonstrated and the effect of compressive strength of concrete, column orientation and slenderness on damage behaviour and residual axial capacity are discussed. The developed assessment method will be of direct relevance to both practitioners and engineers involved with the protective design of buildings.
