dc.description.abstract	To reduce the disastrous consequences caused by explosion, increasing attention has been paid to the blast mitigation of structures while keeping their adequate functions in recent years. In this study, an innovative multi-layer sandwich wall has been developed to provide blast mitigation for protective structures. Such a multi-layer sandwich wall consists of three layers including two steel wire mesh (SWM) reinforced geopolymer based high performance concrete (G-HPC) layers and a metallic tube core (MTC) layer. The blast behavior of the multi-layer sandwich walls under 1.0 kg contact explosion was investigated experimentally and numerically. A total of five sandwich walls were tested to explore the influence of different factors (including the thickness of the front/rear G-HPC layer and MTC layer) on their performance. Subsequently, a finite element model was developed and validated by comparing the numerical results with the experimental data. The findings indicated that the well-designed sandwich walls exhibited excellent anti-blast performance and the rear G-HPC layer remarkably affected the anti-blast performance. In addition, the numerical results could fairly predict the experimental phenomenon.

Abstract:

To reduce the disastrous consequences caused by explosion, increasing attention has been paid to the blast mitigation of structures while keeping their adequate functions in recent years. In this study, an innovative multi-layer sandwich wall has been developed to provide blast mitigation for protective structures. Such a multi-layer sandwich wall consists of three layers including two steel wire mesh (SWM) reinforced geopolymer based high performance concrete (G-HPC) layers and a metallic tube core (MTC) layer. The blast behavior of the multi-layer sandwich walls under 1.0 kg contact explosion was investigated experimentally and numerically. A total of five sandwich walls were tested to explore the influence of different factors (including the thickness of the front/rear G-HPC layer and MTC layer) on their performance. Subsequently, a finite element model was developed and validated by comparing the numerical results with the experimental data. The findings indicated that the well-designed sandwich walls exhibited excellent anti-blast performance and the rear G-HPC layer remarkably affected the anti-blast performance. In addition, the numerical results could fairly predict the experimental phenomenon.
