DETERMINATION OF STRESS-STRAIN STATE OF SHORT ECCENTRICALLY LOADED CONCRETE-FILLED STEEL TUBULAR (CFST) COLUMNS USING FINITE ELEMENT METHOD WITH REDUCING THE PROBLEM FROM THREE-DIMENSIONAL TO TWO-DIMENSIONAL
Abstract and keywords
Abstract (English):
The article presents the derivation of the FEM equations, which make possible to calculate short concrete-filled steel tubular columns in a plane elastic formulation. Steel tube is modeled by 1D bar finite elements. The obtained results are compared with the results of calculations using 3D solid and shell finite elements.

Keywords:
FEM, eccentric compression, numerical methods, CFST columns, concrete
