Abstract:   (416 Views)
Concrete Canvas is a flexible concrete impregnated fabric that hardens on hydration to form a thin, durable water proof and fire-resistant concrete layer. Strength properties of Canvas signify that it could be a blast resistant shell. In this paper, to investigate the concrete canvas shell behavior under blast loads,  the blast behavior of reinforced concrete slabs are compared with prior experimental abservations using coupled analysis. Then the dynamic behavior of two-way concrete canvas shell under near-field blest load is modeled using finite element method. Analysis resultes illustrates failure development, distribution of diagonal and radial cracks on surface and central deflection of concrete canvas shall. Resultes shows that using concrete canvas shell with proper thickness is more resistant under blast loads than conventional slabs.
Keywords: Coupled Analysis, Reinforced Concrete, Roncrete Canvas Shell, Diagonal Crack, Radial Crack, Shell Central Deflection
