Elasticity Damage and Plastic Analyses of Masonry

Abstract:

The relation between stress and strain of masonry material under uniaxial monotonic condition is analyzed and the initial elastic stage is proposed for elastoplastic analyses. Furthermore, plastic damage model and elastic module degradation with plastic strain are investigated. The model describes the effects of irreversible damage: elastic module is fully determined by accumulated plastic strain; compressive stiffness may be recovered during cyclic loading. Based on the model, elastic module degradation and incremental stress-strain equations under multiaxial loading are discussed. Finally masonry shearwall under invariable compressive loading and monotonic shear loading is calculated, and plastic tensional strain before crushing is shown.
