Response of Curved UHPC-CFRP Panels to Close-In Blast Load Effects: A Numerical Study
Protection of critical infrastructure and personnel is a crucial parameter for effective military tactics. With the rapidly evolving landscape of modern warfare, there is a need to investigate the potential of recently developed materials to protect critical infrastructure and personnel. Ultra-high performance concrete (UHPC) and carbon-reinforced fibre plastic (CFRP) are used in the construction industry for retrofitting and rehabilitation for a considerable time now. Many studies in the recent past have presented the blast-mitigation potential of these materials. While the response of UHPC members and CFRP retrofitted blast-damaged members are available in the literature, studies on the response of curved panels strengthened with CFRP fabric are limited. Curved panels have been reported to show better resistance to blast load effects when compared to flat slabs. This paper presents the blast response of a novel UHPC-CFRP composite curved panel made from steel fibre reinforced UHPC and confined by bidirectional CFRP sheets. A high-fidelity numerical model to predict the response of curved UHPC-CFRP panels to far-field blast load effects is reported. Levels of protection offered by the curved panels are recommended for military applications.
