A theoretical analysis and research on the bearing capacity of reinforced concrete members under axial tension and biaxial bending are achieved. A computer program was compiled to study the interaction diagrams (N-M) and (Mx-My) with arbitrary shaped cross-section subjected to axial tension and biaxial bending.
Keywords: reinforced concrete; arbitrary shaped section; axial tension-biaxial bending;  bearing capacity
