Two-way bending behavior of profiled steel sheet dry board composite panel system

This paper describes the structural behavior, analysis, and testing of a structural system known as the profiled steel sheeting dry board (PSSDB) system when applied as two-way floor panels subjected to out-of-plane loading. The system consists of profiled steel sheeting connected to dry boards by self-drilling, self-tapping screws. Analytical models employing the finite element method have been proposed to analyze the panel. This involved two types of modeling: first, the isotropic model, and secondly, the orthotropic equivalent model representing the geometrically orthotropic profiled steel sheeting. It is the simpler latter approach which is of main interest. However, comparison of theoretical to experimental results shows that the isotropic model is more accurate, within reasonable agreement with discrepancies ranging from 2.8% to 12.8%. The ‘orthotropic model’, on the other hand, shows a bigger discrepancy of more than 30%. This indicates that there is a need for improving further the orthotropic model as described in this paper. However, for practical design purposes, the orthotropic model is acceptable since it is more conservative in predicting deflection values of the two-way PSSDB panel. The orthotropic model is preferred over the isotropic model because it is less tedious, requiring less computer memory and computational time, and is more practical for design purposes.

An investigation of lightly profiled sandwich panels subject to local buckling and flexural wrinkling effects

Sandwich panels exhibit various types of failure modes depending on the steel face used. For the flat and lightly profiled sandwich panels, flexural wrinkling is an extremely important design criterion as the behaviour of these panels is governed mainly by flexural wrinkling. However, in the lightly profiled panels, when the depth or spacing of the ribs increases, flat plate buckling between the ribs occurs leading to the failure of the entire panel due to the interaction between local buckling and flexural wrinkling modes. Current design formulae for sandwich panels do not consider such interactive buckling effects. To obtain a safe design solution, this interactive buckling behaviour should be taken into account in the design of lightly profiled sandwich panels. Therefore a research project was undertaken to investigate the interactive buckling behaviour of lightly profiled panels with varying depths and spacings of the ribs using a series of experiments and finite element analyses. A new improved design formula was developed for the safe and economical design of lightly profiled panels that takes into account the interaction between local buckling and flexural wrinkling. This paper presents the details of this investigation, the results and the new design formula.
