SandwichPanel Assemblies: Analytical Model

A method of two dimensional analysis of sandwich panel assemblies used as main resisting elements of building structures is provided. This method is based on the equivalent wide column frame analogy, with due consideration given to the composite nature of materials and to the nonlinear behavior of the connection system. A simplified structural idealization is adopted to predict the theoretical response of a six story two cell box structure, subject to a series of loading conditions. Theoretical and experimental results compare favorably. The influence of secondary effect of shear deformation, and the effective width of floor beams on the structural response is also taken into account.
