Abstract (EN): A model is proposed for the force-deformation behaviour of reinforced concrete members under biaxial loading with axial force. It embodies an existing uniaxial hysteretic model with piecewise linear behaviour as the foundation for its development and proceeds from analogy and comparison with the biaxial formulation of the Bouc-Wen smooth hysteretic model previously presented by other authors. The proposed biaxial model formulation requires the same information needed for the corresponding uniaxial model and introduces an additional correcting term into the existing uniaxial model coupling the two loading directions. The validity of the presented model is demonstrated through the analytical simulation of available biaxial experiments on reinforced concrete columns. The presented model is proven to be efficient and establishes a simple form of analysing reinforced concrete structures in which biaxial interaction should be considered.
