Abstract
This paper describes briefly the stability analyses of doubly corrugated thin-walled steel panels which are used as a solution for buildings and roofing structures. As an example of such system the ABM MIC 120 prefabrication technology is chosen where factory on wheels makes cold-formed arch steel buildings or roofs in a very short period of time as self-supporting panels. The main problem of such structures lies in the lack of proper theoretical model of the element due to its complex geometry. In order to understand the panel behavior, linear and non-linear stability analyses are carried out in ABAQUS. The achieved results are compared with preliminary compression tests performed on steel samples. The main goal of this paper is to show how the complex geometry of such panel influences the magnitude of axial compression critical force.
