摘要：In some fields of industry, such as stowage works, strongly safety assessment should be ensured, so it is important to design constructions, like platforms, which would withstand heavy static loading and, in emergences situations, to withstand the same bulk, dropped from the predicted height, with the ability to damp it. In order to perform a FEM structural analysis of such structure, the accurate material characteristics should be known. For this reason, four types of specimens - standard flat, tube contoured and the same ones containing longitudinal weld, welded in the longitudinal direction using electrodes CT36, were manufactured from a stainless 321 steel sheet and tested in order to define mechanical properties of the material. Using the obtained true stress-strain curves, the static analysis of pillar compression was carried out and the simulation of its behaviour, if a heavy weight structure will be dropped from a height of 5 meters, was performed. The static analysis showed that, when the static load is 40 tons, the pillar structure satisfies high safety requirements. The dynamic impact simulation showed that the most reasonable load for the pillar is 9 – 11 tons and, if it is not overloaded, the longitudinal weld does not influence an adverse effect and the pillar deforms smoothly without cracks.
