New Phase

Recent advancement in manufacturing technology has initiated a new phase of buckling structures analysis and structural design research development. As the ability to manufacture stiffeners in complex shapes has become increasingly more sophisticated, researchers are able to further enhance the design of thin-walled stiffeners. This paper presents an attempt to discover a structural design which employs the use of sub-stiffeners and the ability to retain maximal buckling load. FEM analysis was performed on compression loaded rectangular stiffened panels clamped on all sides to determine optimal attributes of two panel concepts: (1) stiffeners height changes according to sinusoidal law across the panel width, (2) stiffeners area changes according to sinusoidal law across the panel width. In both cases, total volume of the material was held constant. Non-dimensional parameters of the optimal panels were obtained. It was found that there was a positive correlation between the amount of change in buckling patterns caused by a sub-stiffener, and the amount of initial buckling load which could be obtained.

Independent Calculation

Due to the increase of computing capabilities of standard processing units, it is possible to perform complex analyses, considering a number of nonlinearities, such as geometric, material and boundary (contact) even on personal computers. In the paper, the authors have analysed the efficiency and accuracy of standard PC’s FEM calculations performed in Abaqus CAE 2017 software on the example of a critical load assessment of a thin-walled steel column element with selected nonlinearities. A cross-section shape of a built-up column used by an international steel structures manufacturer was adopted. The analysis serves to check the behavior of their product. Several types of FEM analysis, strictly based on the EN standard regulations were performed. In turn, the relation of computational time to the adopted analysis type was obtained. Moreover, the produced load values in different types of independent calculation were compared and analysed. A possible future development in the field, based mainly on full-scale experimental tests, was also highlighted.
