“…Simultaneously, in “traditional design” stabilisation of particular elements, e.g., purlins, by sheeting is much more eagerly taken into account (this problem was analysed, e.g., in [ 13 ]), while the diaphragm effect is neglected; thus, extra global stiffening of the structure by sheeting is considered beneficial. However, it has to be remembered that regardless of possible considering the stressed-skin actions of the cladding, it brings extra structural stiffness to a certain extent.…”

In stressed-skin design, the cladding stiffening effect on structures is taken into account. However, the “traditional” design is more usual, wherein this effect is neglected. Even if the diaphragm actions are not regarded, in particular cases such as big sheds (and others), the parasitic (unwanted) stressed-skin action may occur with the result of leakage or even failure. The structures of this kind have already been built. Thus, an important question arises: How can one assess them if there is a need to correct or redesign them? What kind of non-destructive approach can be used to achieve that? Experimental tests of small-scale shear panels made of trapezoidal sheeting were designed in order to observe the behaviour of the diaphragm under increasing and repeated load. The tests were oriented toward force–displacement relations and strains in selected areas of the sheeting. The results revealed nonlinear, hysteretic force–displacement behaviour of the panel and the occurrence of the persistent deflections and stresses which remain even after the unloading. The relation among the stresses, force–displacement paths and modes of failure can be potentially used in monitoring systems of existing buildings in terms of parasitic stressed-skin action.

Nowadays buildings based on lightweight steel skeletons are widespread in civil and industrial engineering. The trapezoidal sheet or roof sandwich panels fastened to thin-walled cold-formed purlins can be used as the building envelopes. In this paper the questions of numerical analysis of thin-walled Z-purlins in the coverings made of sandwich panels are studied. Numerical analyses are performed in the program MSC.NASTRAN. A full scale model of the roof with purlins and sandwich panels is considered. Numerical analyses are based on the laboratory experiments. Results of described analyses are compared with the results of tests. These researches are done to investigate a behavior of the roof system consisted of Z-purlins and sandwich panels and to develop a correct finite element model for the design of cold-formed purlins supported by sandwich panels.

“…New stability problems were also originated when roof cladding elements were assumed to provide support for compressed top flanges of purlins or beams of frames [8,9,10,11]. Roof cladding are often made of profiled steel plates.…”
