| description | This paper discusses the numerical investigation on steel – concrete composite slabs under blast loading. The study was conducted using finite element software and the finite element model of the steel – concrete composite slabs was validated against a disparate test data. The model was used to investigate key parameter in particular; the diameter of mesh reinforcement used in the steel – concrete composite slabs. The validation results show that the computed model of steel – concrete composite slabs can almost replicate the result from the experimental. Thus, the model that have been computed was extended for blast simulation using CONWEP. CONWEP is a blast load function available in Abaqus FEA. The blast-profiles from the CONWEP was verified against the result obtained from a disparate field test. The results suggest the CONWEP is able to simulate the blast-pressure profiles with sufficient accuracy. By using CONWEP in Abaqus, the validate composite slabs were subjected to various blast loading cases. From the study, it was found that the pressure is affected by the stand-off distance and the weight of the mass explosive. Which the higher the explosive mass and the shorter standoff distance used will produce high impulse. High impulse load resulted a higher displacement on the steel – concrete composite slabs. Finally, from the parametric study, the limit diameter mesh reinforcement to use in steel – concrete composite slabs is 8 mm because increasing it more will not give significant resistance toward blast load. |
