dc.description.abstract	Engineering structures may experience multiple blast loadings owing to accidental explosions and terrorist attacks, however, few studies focused on the multiple blast loading effect on the structures.

The effects of the thickness and location of UHMWPE FRC on the multiple blast behavior of the SWM reinforced G-HPC slab were examined by parametric analysis.

The SWM reinforced G-HPC slab protected by UHMWPE FRC has better multiple blast resistance, and the UHMWPE FRC effectively mitigated the blast loading and further reduced the damage to the slab. In addition, the findings of the parametric analysis revealed that UHMWPE FRC was more effective to enhance the blast resistance of a slab as it was placed on the bottom surface.

Abstract:

Engineering structures may experience multiple blast loadings owing to accidental explosions and terrorist attacks, however, few studies focused on the multiple blast loading effect on the structures. In this study, the multiple blast resistance of the steel wire mesh (SWM) reinforced geopolymer based high performance concrete (G-HPC) slabs protected by ultra-high molecular weight polyethylene (UHMWPE) fiber reinforced cloth (FRC) were investigated by experimental and numerical studies. The effects of the thickness and location of UHMWPE FRC on the multiple blast behavior of the SWM reinforced G-HPC slab were examined by parametric analysis. The failure modes and the blast-resistant mechanism of the slabs were revealed. The experimental results indicated that the SWM reinforced G-HPC slab exhibited superior resistance against multiple blast loadings as compared to the plain G-HPC slab. The SWM reinforced G-HPC slab protected by UHMWPE FRC has better multiple blast resistance, and the UHMWPE FRC effectively mitigated the blast loading and further reduced the damage to the slab. In addition, the findings of the parametric analysis revealed that UHMWPE FRC was more effective to enhance the blast resistance of a slab as it was placed on the bottom surface.
