The paper presents section model for analysis of the resistance of masonry structures with rectangle cross-section subjected to the eccentric compression. The nonlinear stress-strain relationship for masonry in compression is assumed taking into account the effect of masonry softening. The formulae for normalized ultimate axial force and n mu and bending moment m mu are derived in the analytical form by integrating the cross-sectional equilibrium equations. The calculated results are presented in the form of interaction diagrams and compared with those based on the parabola-rectangle diagram for masonry in compression. It has been shown that the section resistance is strongly influenced by the masonry softening and depends on the limiting value ε mu for masonry in compression.
