The paper presents a finite element method for in‑plane analysis of clay masonry walls. The finite element model treats masonry as elastic brick continuum elements linked by mortar joint elements that exhibit high compressive, low tensile, and limited shear strengths, with material parameters calibrated from uniaxial brick and masonry panel tests and benchmarked against deep‑beam experiments. The model successfully reproduces masonry’s nonlinear behavior due to material nonlinearity and progressive joint failure.
A method for the in-plane analysis of clay masonry walls is presented. The proposed finite element model reproduces the nonlinear characteristics of masonry caused by material nonlinearity and progressivee joint failure. Masonry is considered as an assemblage of elastic brick continuum elements acting in conjunction with linkage elements simulating the mortar joints. The joint elements are assumed to have high compressive strength (with nonlinear deformation characteristics), low tensile strength, and limited shear strength depending upon the bond strength and degree of compression present. The material properties for this model are determined from uniaxial tests on bricks and masonry panels. Tests on a masonry deep beam are used as a basis for comparison between predicted theory and experimental evidence.
