NUMERICAL MODELING OF CONCRETE FILLED TUBULAR COLUMNS WITH SEPARABLE JOINTS BY FINITE ELEMENT METHOD
Journal Title: Збірник наукових праць Українського державного університету залізничного транспорту - Year 2017, Vol 172, Issue 6
Abstract
This paper deals with results of numerical modeling of concrete filled tubular samples with separable flange joint, with separable joints made with the help of longitudinal ribs and steel couplings as well as samples without joints. For all investigated samples that were previously tested experimentally, identical real mathematical models were created for which with the help of numerical simulation in the software complex Femap, the stress-strain state was investigated and graphic representations of the main stresses were presented. The stresses in the compressed and stretched zone of the concrete filled tubular element were compared in accordance with the experimental data and, consequently, the results of numerical simulation. The mean square deviation and the coefficient of variation of the data obtained varied within the range of 5-7%, which is admissible and suggests that the modeling results correspond to the experiment.
