Název v původním jazyce

Determination of a 1D element stiffness for a steel-concrete-steel structure modelling via plane element layering

Popis výsledku v původním jazyce

The method of plane element layering is based on modelling of each material layer separately by FEM plane elements, which are connected by 1D elements in each node of a finite element mesh. Previous studies have shown, that results of the analysis are certainly dependent on the stiffness of 1D elements. Therefore, the stiffness must be determined. The first part of the paper is focused on the motivation and a brief description of the considered modelling method. To correlate the results from the own analysis with the real behaviour of the steel-concrete-steel structure, the set of already performed tests is also shown. These tests are used for the comparison with numerical calculation results, while the stiffness of 1D elements is modified for the sufficient compliance. According to this analysis, a discussion is held on appropriate adjustments of the model.
