Elevated Temperature Behavior of Impact-Induced Partially Damaged Concrete
Designing protective structures capable of withstanding the combined extreme actions of impact/blast and fire necessitates the accurate prediction of material properties under the coupled effects of high-strain-rate and subsequent elevated temperature loadings. An extensive experimental program was being carried out in the Civil Engineering Laboratories at Monash University to investigate the post- impact fire properties of plain self-compacting concrete (SCC) material and the results are presented in this paper. This will help in evaluating whether partially damaged concrete elements can further sustain additional stresses in case of a subsequent fire outbreak. Specimens have undergone interrupted high-strain-rate compressive loading, controlled locally at defined levels of axial displacement, to account for different deformation states. Results indicate that the mechanical behavior of concrete subject to post-impact fire scenarios is dependent on the rate of loading, the damage history and the fire temperature to which it is subsequently exposed.
