“…The division of the network into spatial tetrahedral meshes allows one to easily locate single transformed folded shells and bar constructions supporting these segments in the three-dimensional space. The above-mentioned problems show the wide possibilities of using the specific orthotropic geometric and mechanical properties of folded sheets in rational shaping of the transformed roof coatings [29,30]. A respective analysis should be carried out at different levels: single points, walls or folds, smooth shell models, and ribbed structures composed of many smooth transformed shell segments [31,32].…”

This article provides a novel insight into specific properties of flat folded sheets transformed elastically into building roof shells. Elastic twist transformations of the sheets resulting from the arrangement of the sheets on two skew roof directrices cause changes in the geometric and mechanical sheet properties of the roof shell sheeting composed of these sheets. Regular smooth-ruled surfaces and their characteristic lines are used in the analysis of changes in the geometric properties. In the analysis of the mechanical changes, the constitutive relations and complex state of stresses are considered. The analysis is carried out on the basis of the results of the experimental tests and FEM computer simulations. They have led to the development of such a method of shaping of the effectively transformed folded covers that ensures the initial effort of each shell fold to be the smallest possible.

Compression behaviour of trapezoidal steel sheets with transverse corrugations

et al. 2019

Nominated for the Bernt Johansson Outstanding Paper Awards at Nordic Steel 2019 Over the past few decades, the cold‐formed steel industry has developed a manufacturing technique for producing self‐supporting arches from trapezoidal steel sheets. The press‐forming procedure is based on introducing transverse corrugations into the main direction of the flat profile in order to bend it. The main problem is that these indentations, which are essential to curve the profile, change the effective properties of the original steel sheet. Currently, there is no design code or standardized test procedure that can be used to obtain the effective properties of the corrugated profile. This research project analyses the behaviour of the corrugated profile when it is subjected to pure compression and compares it with the behaviour of the flat profile.
