Abstract

The article deals with the possibilities of connecting thin-walled purlins and supporting structures. The presented research is part of it the designing of large-scale halls field. For this type of construction the using of thin-walled purlins of higher structural heights is recommended. The behavior of the structure is highly influenced by different types of joints, by their number and also by other things. For example, geometrical and physical non-linearity must be including in numerical analysis. Experimental testing is also highly required. The main aim of the article is demonstration of parametric studies of a comprehensive series of experiments. The experiment results are presented in the context of the current design code. The evaluation is performed in the form of interaction (M/N) diagrams. Parametric study includes different thicknesses of steel, selected Z-purlins heights and several connection methods. The paper also contains a detailed determination of material properties of steel by tensile tests.
