Effect of Panel Stiffness on Resistance of Cladding Panels to Blast Loading

Abstract
Presented in this paper is the study of the effect of panel stiffness on the resistance of cladding panels subjected to blast loading. In many situations the size of a cladding panel has largely been decided by architects, leaving engineers to design the cross section, which directly influences the panel stiffness. By introducing the concept of a deformed shape function that is independent of panel stiffness and loading levels, the relative effect of panel stiffness, the material properties, and blast loading levels on panel deformation and forces transferred to fixings can be assessed without the need to actually specify the deformed shape function. It was found that these relative effects of panel stiffness and loading levels also depend on whether the panel is in the impulsive or quasi-static loading range. The theoretical predictions were compared with results from finite element analyses using DYNA3D, and good agreement was obtained. Though the mathematical derivation is complex, the findings are easy to use and have wide practical applications.
