Abstract

In this paper, the behavior of deep trapezoidal sheeting with perforated webs is studied. The analyzed panel has longitudinal stiffeners both in the webs and flanges, which improves the load-bearing capacity but makes the behavior more complicated. The considered panel is produced with and without web perforations. When web perforation is applied, it is located in the middle part of the web. The primary aim of web perforation is to enhance noise resistance, but it also has an influence on the static behavior. Because reliable design rules for web-perforated trapezoidal sheeting panels are not available, an experimental program is undertaken: panels with and without web perforations are tested in parallel. The test setup and specimens are designed to provide information on all the behavior modes. On the basis of the test results, it is possible to define the degrading effect of web perforation on the rigidity, bending, and shear resistances and on the resistance to direct transverse forces close to and far from the panel end. The experimental results are compared with proposals found in the relevant literature. On the basis of the test results, reduction factors might be proposed to consider the effect of web perforation in the design of the investigated sheeting panel.
