Abstract When crest-fixed corrugated steel roof claddings are subjected to wind uplift loading, local dimpling failures occur prematurely at their screwed connections because of the large stress concentrations around the fastener holes. Once the screwed crests are locally dimpled, high wind events such as storms and cyclones can cause severe fatigue cracking and pull-through failures, leading to the loss of entire corrugated roof cladding. Therefore, the pull-through capacity is an important parameter governing the wind uplift strength of corrugated roof claddings. This paper presents the details of a numerical investigation of the local dimpling behaviour of corrugated claddings under static wind uplift loading. It includes the details of the developed finite element model and validation, an extensive parametric study, and the results including a design equation to determine the pull-through capacity of crest-fixed corrugated cladding.
Highlights Developed FE model of corrugated cladding and validated using experimental results. Localised plastic dimpling based pull-through failure occurred at the screw holes. Conducted a parametric study that included important influential parameters. Pull-through capacity was highly dependent on geometry, thickness and span. Developed new pull-through capacity equation for crest-fixed corrugated CFS cladding.
